When is the best time to use a pregnancy test. Are there any mistakes in pregnancy tests? Tests of Russian manufacturers, which most often can show a false positive result

With the invention of tests for an early, and most importantly, a simple definition of pregnancy, women can become happy earlier than the prescribed 6-8 weeks of an interesting position, when the gynecologist confirms the fact of the development of a new life.

Two cherished stripes bring a lot of joyful emotions to future parents. In this article we will talk about all the intricacies of home express diagnostics of pregnancy, teach you how to do the test correctly and understand the result.

How does the test work?

All tests are based on a single mechanism - the determination of the hormone chorionic gonadotropin or hCG in the urine, the production of which begins from the moment the villi of the growing placenta enter the uterus, i.e. embryo attachment. Its amount grows every day, but at the very beginning, the growth of this hormone can only be determined by a special study of venous blood (the result will be positive 5 days earlier than the most sensitive tests begin to strip).

Most rapid tests start at 25 mUI hCG. Some manufacturers write on packages that the test is sensitive already at 10 mUI hCG, but it is difficult to prove this. As pharmacists say, this is more a publicity stunt than the truth. Another tricky advertising move is the inscriptions that the test has the highest probability of detecting pregnancy before the delay, an accuracy of 99.5-99%, etc.

If you have a regular menstrual cycle

The release of a mature egg, ready for fertilization, occurs in the middle of the cycle. With a 30-day cycle, this is the 15th day, with the 28th - 14th day. Fertilization can occur over the next two days. After the fusion of the egg with the sperm for another 4-5 days, it "floats" to the placentation site in the uterus. Those. At about the 22nd day of the cycle, according to the blood test, you can already see the growing hCG. The most sensitive and high-quality tests can show 2 strips 4 more days before the expected menstruation, when the level of hCG in the urine becomes more than 25 mUI.

Thus, you can do a highly sensitive test on the 26th day of the cycle with a 30-day cycle, and on the 24th day with a 28-day cycle!

If you have an irregular menstrual cycle

You can determine when ovulation has occurred using:

• an increase in the level of basal temperature;
• appearance.

Having designated for yourself the date of approximate ovulation, 12 days are added to this number - it is already possible to detect an increase in hCG in the blood (see). 15 days after the approximate ovulation, you can do the test with high sensitivity.

What time of day should a pregnancy test be done?

Typically, the instructions for the test strips do not recommend what time of day to test. This means that during pregnancy the test will show 2 strips at any time.

Gynecologists advise doing the test in the morning using night urine. In this case, the result will be reliable, especially in the early stages of pregnancy. If you test during the day, there is a possibility of error, since the urine is not so concentrated due to the fluid consumed during the day. The same is possible if the test is done in the evening - the hCG content in the urine will be lower. If there is a need to test during the day, then it is better to do this after four hours of abstinence from urination, while limiting the use of fluids to obtain more concentrated urine.

General rules for the correct use of pregnancy tests

• The pregnancy test must be stored under the conditions indicated by the manufacturer on the packaging;
• The dough packaging should not be damaged;
• Expired tests cannot be used;
• You cannot use the same test 2 times;
• It is best to do a night urine test;
• The dough package is opened immediately before use;
• Before urinating, wash and dry yourself with a towel;
• Urination should be carried out in a clean container;
• It is very important to strictly follow the instructions: lower the test in the urine exactly to the indicated level, keep it in the urine for no less and no more than the recommended time, evaluate the result only at the indicated time.

Pregnancy test - instructions for use

There are many test options available in pharmacies. They all have a different cost, but they equally promise an accurate result. Let's figure out how to use them correctly and which ones will still be the most reliable.

• The most popular and reliable are Frautest and Evitest pregnancy tests. The tests of these German manufacturers occupy an average price niche (100-140 rubles), but they do not sin with false results.
• All other tests can be considered equally reliable, provided they are used correctly, especially with regard to the time to delay. The most reliable result can be obtained by testing in the first 1-3 days of missed periods.
• The cheaper the test, the cheaper the reagent used in it.

Strip test

Popular and inexpensive tests in the form of a paper strip coated with a layer of antibodies in hCG. The hormone in the urine reacts with the impregnation of the strip, and a second strip appears on the test.
Test application instructions... For testing, you will need a clean container that collects a few milliliters of urine. The test is immersed in the urine tip to the indicated mark and held for 10 seconds. The result is assessed within 1-10 minutes (the less hCG in the urine, the later the 2nd strip will appear).
Reliability - from the first day of the delay.
Plus: cheap.
Cons: not convenient to use, does not show the result until the delay, it can be wrong.

Tablet test

Produced in a special box with two windows. The principle of operation is the same as for strip test. Includes urine collection cup and pipette.
Instruction. You need to drip 4 drops of urine into one window. The result is assessed in the second window after 1-10 minutes (1 or 2 strips).
Reliability - from the first day of the delay. Until the delay does not show pregnancy.
Pros: Inexpensive, easy to read results.
Negative: Requires a lot of action.

Inkjet test

The name itself suggests that it can be placed under a stream of urine.
Instruction. The test is placed under a stream of urine or in a container with urine with a filter tip for 10 seconds. The result is assessed after 1-10 minutes in a special window (1 or 2 strips).
Reliability - determines hCG 5 days before the delay. One of the best tests.
Pros: precise, most comfortable to use.
Minus: expensive.

Electronic pregnancy test

Another name is digital. The most advanced rapid test.
Instruction. The test is dipped into the urine with the filter tip before soaking. The result is assessed after 3 minutes: in case of pregnancy, a “+” sign or “pregnansy” appears in the window.
Credibility. May show pregnancy up to 4 days before the delay. Considered 99% accurate when tested 2 days in advance of your expected period.
Pros: The result is impossible to misjudge, the most highly sensitive.
Cons: the result is visible only for about a day, then the inscription disappears, leaving proof of pregnancy as a keepsake will not work. Most expensive.

Can the test result be negative during pregnancy?

HCG levels rise differently for everyone. Within 2 weeks of the delay, the test may still be negative if the woman has endocrine dysfunction or is at risk of miscarriage. A false negative test will also be if it is used too early, some women begin to do tests from the day of possible conception. Well, there is nothing harmful in this, but is it worth tormenting yourself, expecting a miracle?

Another reason is non-compliance with the rules for using the test.

False positive test result

This happens in the following cases:

• in the first 2 months after delivery;
• ovarian dysfunction;
• the development of a hormone-producing tumor (chorioncarcinoma,);
• when using an expired test.

Is the result of a test taken during your period reliable?

For some women, menstruation may continue during pregnancy. However, menstrual blood does not in any way affect the sensitivity of the test, so the result will be reliable. Even if a woman did a test in urine, stained with bloody discharge, if there is a proper level of hCG in her, the test will show 2 bright stripes.

Ectopic pregnancy test results

In an ectopic pregnancy, as you know, the attachment of the ovum occurs outside the uterus, more often in the fallopian tube. But hCG begins to be produced in this case as well. A feature is the lack of hCG growth or its small growth.

So a normal pregnancy test will show the same 2 strips. Probably, the second strip will be barely visible or more blurred than in a normal pregnancy, and the test will become positive only after the onset of a delay in menstruation.

A special INEXSCREEN test allows you to suspect an ectopic pregnancy a couple of weeks after the delay. Diagnosis is based on the identification of the level of the modified isoform in the composition of hCG, which in an ectopic pregnancy is significantly lower than the prescribed 10% characteristic of a normal pregnancy.

Test results for a frozen pregnancy

If a clear, several times positive result obtained within a week becomes doubtful, and then the test shows only one strip at all - there is a high probability that the pregnancy is frozen. An urgent need to visit a doctor.

How to decipher a dubious result?

A dubious result arises when there is doubt whether there is a second streak. It can be faintly visible, blurred or slightly translucent, as it were from the inside. Causes:

• a low level of hCG, borderline with the minimum at which the test becomes sensitive;
• unusable test, non-compliance with testing rules;
• a great desire of a woman to see 2 strips. Very often we wishful thinking.

What to do if the test shows a questionable result? Repeat it in a few days, or better - in 1-2 days after the delay.

Anti-rating of pregnancy tests

Unfortunately, it also happens that with strict adherence to the rules for conducting express diagnostics, a pregnancy test shows a result that does not correspond to reality. Tests sin with false positive and negative results:

The most proven way to detect pregnancy is to have a blood test. Blood levels of certain hormones increase throughout pregnancy. This is one of the most reliable methods for determining a special situation.

But not every woman can conduct such an analysis, sometimes the reason is reluctance, sometimes there is simply no way. And many simply do not see the point in spending money when there is an alternative way to resolve the issue.

How easy it is to detect pregnancy

The easiest way to check (positive result)

The most affordable, simplest way to determine pregnancy is a test. You can buy it at absolutely any pharmacy. The price range is huge. It is often a small, narrow strip that is treated with a special reagent.

This type of diagnosis is quite accurate. Many manufacturers claim that the accuracy can be up to 99%. But it still depends on when you will make the diagnosis. How many days after conception can the test show pregnancy? On the packages they write that starting from the first day of the absence of menstruation, you can use the tester.

But after all, many begin to feel internal changes even before the onset of the monthly cycle. Experts say that the accuracy of such methods depends on the timing and there are more sensitive strips, there are less. But if you do everything on time, then almost any test will show the result.

Do not do research immediately after conception. The level of chorionic hormone, thanks to which pregnancy is determined, will increase only after a while. Usually, a sufficient period is seven days for the test to show pregnancy, because many are interested in the question - how many days you can use it after conception. Therefore, it is possible, but still not recommended, to use a test to determine pregnancy before delay. This will not always be an accurate result (you need to be prepared for the fact that it will be false), but sometimes it can be determined in advance.

Positive and negative result

Ovulation occurs around the middle of the cycle. But fertilization may not occur on the same day, but within a week. And the level of the hormone will increase only on the fourteenth day after ovulation.

It makes no sense to use a test for ovulation, if only fertilization (fertilization occurs after conception!) Occurred in the last cycle. It only lasts 24 to 48 hours. During this period, the chances of getting pregnant are very high. When ovulation is over, the chances of getting pregnant are virtually nonexistent. An exception is late ovulation, before menstruation.

In the absence of menstruation, it is necessary to make a diagnosis and if it shows a positive result, then the pregnancy was determined. If it is negative, it is worth repeating the procedure after a while to exclude a false result.

Home diagnostic methods

Tablet version of the test

Now there are many ways to determine your condition yourself at home, which will help to identify pregnancy within a couple of days after ovulation using a test. On the shelves of pharmacies, we can see several types of tests:

• strip test, waiting for a reaction from three to five minutes;
• tablet, reactions after five minutes;
• inkjet, a couple of seconds is enough;
• digital or electronic, operates on the inkjet principle.

Convenient in that it makes no sense to look out for the appearance of a strip. The result is shown on the screen.

Name	Description	Price	Accuracy (on a five-point scale, depending on the period)
Babycheck	Dropping strip container with urine. Susceptibility from 25 mME / ml	From 10 to 100 rubles	3
Evitest Proof	A device with a special window into which you need to add a few drops of urine. Susceptibility from 10-25 mME / ml.	from 50 to 150 rubles	4
Frautest COMFORT	Without the need to collect urine in a reservoir, the method of application comes from the name. The most convenient way to determine the state of pregnancy with a few days of delay. Susceptibility 10 mME / ml	from 150 to 250 rubles	5

Before checking. Check the expiration date of the product. The lower the sensitivity figure, the more accurate diagnosis is possible in the early stages.

Terms of determination after implantation

After how many days it is possible to make a pregnancy test after implantation. The devices, which have a sensitivity of 10 mU / ml, can be used to determine pregnancy from the seventh to the tenth day after conception or implantation. Therefore, it makes no sense to conduct tests before this period. Even the most sensitive can give false positive and negative results before delay. Because the level of hCG is needed (human gene, with the help of this hormone pregnancy is determined) will not reach the required level. In order not to torture yourself in vain, the test should be carried out ten days after the menstruation has not come. Or after two days, then for confirmation after some time.

The process of conception goes something like this

The optimal days when the test can be done after implantation depends on:

• how sensitive and high-quality the tester is;
• what is the condition. When there is a threat of miscarriage, hormones are produced more slowly in relation to normal pregnancy;
• correctness of implementation. It is necessary to do everything as written, according to the instructions.

If the results are negative, but menstruation still has not started, it is worth repeating the procedure.

How the tester works

Sets the level of hCG in urine

All pregnancy tests work according to the same principle. They determine the level of hCG in the urine. This hormone begins to be produced when the placenta develops. In women, under normal conditions, it is normal - it is from 0 to 5 mU / ml. Starting from the first week of fertilization, the level of this hormone and its concentration increases.

Testers are distinguished by sensitivity into two types:

• those that determine the concentration of hCG from 10 mU / ml. A similar specimen can determine the state as early as five, seven days after fertilization;
• those that can determine the concentration from 25 mU / ml. They are the cheapest in the pharmacy and determine the condition at a later date.

So the principle of work.

1. They set the hCG level.
2. The determination is possible due to the fact that each tester has an antibody to hCG. When the level is sufficient, antibodies react.
3. Red streaks appear upon reaction.
4. It can be determined before the start of the menstrual cycle, and then. After a delay, the result will be more accurate. But you can check and repeat.
5. The timing depends on the timing of ovulation.

It is best to conduct a pregnancy test in the morning, then it will show a true result. Because the urine is most concentrated in the morning.

When a second strip appears, the result is positive with a high probability (approximately 99%). A weak streak is also considered a positive result, but the hCG level is still too weak.

In some cases, it is possible to get a false positive result - this can be due to certain medications or if there is a tumor.

New unused device

Sometimes there may be a false negative. It happens:

• when the concentration of the hormone has not yet reached the required level;
• in case of impaired renal function;
• Too much liquid was drunk before the test.

Correct application of the instruction

The principle of the test, which will show whether you are pregnant or not, is very simple:

• it is necessary to wait for a certain day (whether it is a delay or you have calculated certain days from the moment of ovulation);
• in the morning you collect urine in some container (the container must be clean);
• lower the test strip to a certain mark for a few seconds;
• then you need to wait for this from three to five minutes;
• place the strip on a clean surface;
• after ten minutes the test is invalid;
• one bright red stripe is negative;
• two bright red stripes - positive;
• other cases (when the strip appeared, but the second - the result is invalid, or, when the second strip is barely noticeable, it is worth doing another test after a while).

Pregnancy is a certain state of the body, which means the birth of a baby, after a certain period of time. It can be identified by some of the symptoms.

When a woman is looking forward to the birth of her first child, she is trying to find any hints of pregnancy in all the changes in her body. Many believe that when irritability or nausea appears, that's all, they are in a position! Although, most mothers really found out about their pregnancy precisely by these signs. Of course, all this may suggest the presence of pregnancy, but, unfortunately, such signs do not always arise when determining this interesting position.

How was pregnancy recognized in women in ancient people?

A thousand years ago, ancient people were already able to recognize the first signs of pregnancy.

Ancient Egyptians, in order to find out about the woman's interesting situation, they prepared a special "test drink" for her , which consisted of a special herb and milk from the mother, who was breastfeeding the boy. If such a mixture after its use caused the woman to vomit, then this verdict was confirmed - she is pregnant!

Previously, pregnancy was determined by numerous signs

And here old Jews asked women who might have a pregnancy, walk on the soft grass. After that, they studied her tracks and made certain conclusions. But, unfortunately, the details of how exactly they could determine pregnancy by prints have not reached our days.

The main symptoms and signs of pregnancy

The real existence of pregnancy in a woman can only be confirmed tests that will show an increased level of hCG in her blood , or if the doctor listen to the baby's heartbeat in the womb, or ultrasound results ... All other methods are only possible signs and symptoms.

Accurate signs of pregnancy

Elevated hCG levels - the presence of a large amount of pregnancy hormones in the woman's blood. It begins to grow a week or 10 days after the conception process. This analysis is quite accurate in determining pregnancy. Having donated her blood from a vein to any laboratory, a woman will be able to find out about her situation, even before her period is late.

Listening to your baby's heartbeat is carried out by a gynecologist using an electronic or wooden stethoscope. The doctor can hear the baby's small heart beating in the womb at 10-12 weeks. Its heart rate is between 120 and 160 beats per minute.

Ultrasound - this is an ultrasound examination of a woman, which is preferably carried out at 7-12 weeks. With its help, you can establish the exact duration of pregnancy from 2 or 3 weeks.

The doctor can hear the fetal heartbeat with a special device

TO signs of pregnancy can include such phenomena or sensations as:

• Small discharge in the form of a few brown drops that you can find on your panties. This may not be the start of your monthly menstrual cycle, but implantation bleeding ... It occurs as a result of the search for the uterine wall, a cell that will eventually become a child. She, as it were, "travels" through the mother's sexual passages and is looking for a suitable place for herself where she will grow and develop in the future. it one of the earliest signs which, in general, cannot always prove itself.
• Constant fatigue and feeling of weakness... Most women who are not yet aware of their situation believe that they are simply tired or sick. But this may be true. Because the first reason for weakness is decreased immunity ... Some expectant mothers may even have a runny nose and cough.
• Increase in basal body temperature... If you think that you will have a baby, then do not be lazy to monitor your basal body temperature during the menstrual cycle. Are you really pregnant if your the temperature will rise to 37 degrees , or abruptly will go down one day in the II-nd phase of the bleeding cycle. This process is referred to as "implantation sinking", the main reasons for which are a decrease in the production phase of the hormone progesterone in the middle of the second phase of the cycle, which is responsible for the state of temperature. Or, when the hormone estrogen begins to be released. He is responsible for lowering the temperature.
• Sensitive breasts... In cases where at some point you have an increased sensitivity of the nipples, then it is likely that you have a pregnancy. This symptom may appear only 14 days after conception ... Your breasts can make themselves felt even with the most gentle touch. It may also slightly swell and hurt a little. Darkened skin around the nipple areola may also indicate pregnancy.

The emergence of noticeable tubercles of Montgomer, which are on the nipple of the breast. They are tiny lumps on the areola of the breast that resemble goose bumps ... These bumps are absolutely harmless, but their appearance can signal an interesting position of a woman.

Nausea, intense sensitivity to certain odors- This is a classic well-known sign of pregnancy. It makes itself felt with 3rd to 8th week after the conception process ... More than half of expectant mothers met with similar and unpleasant sensations. This symptom may also appear when you are very overeating or poisoned. Therefore, do not rush to rejoice if you have such an indicator in the morning.

Insomnia or sleep disturbance appear in many pregnant women, due to certain changes in their body. That is, despite the fact that they go to bed early, expectant mothers still do not get enough sleep. They can also fall asleep in the middle of the day , even in the workplace. If your robot is serious and responsible enough, then it is advisable for you to change it, or move to a quieter department. On this occasion, it is not worth much worried. It's just that the body gives all sorts of signs about its new status.

• Delayed monthly menstrual cycle considered the most common sign of pregnancy. Noticing its failure, we begin to assure ourselves that we are pregnant and immediately run to the pharmacy for the test. But, in the event that a woman has an irregular bleeding cycle, then you should not rely only on a delay.
• Lumbar pain or in the back can become quite tangible. Such unexpected "lumbago" in the lower back of the expectant mother can manifest itself throughout the entire period of bearing the baby, periodically letting itself know.
• Unpleasant bloating may occur due to the fact that during pregnancy the woman's intestines become "lazy". He ceases to monitor well the level and process of gas formation. Also, a similar phenomenon can be felt because the intestinal walls begin to swell a little.
• Frequent urge to urinate... Two weeks after conceiving a baby, a woman can feel frequent urge to use the toilet, at a small ... They are explained by what happens in her body change in her hormonal background - stretching of the uterus and growth of the fetus, which constantly presses on the outer membranes of the bladder.

Frequent urination can be a sign of pregnancy.

How do you know if you are pregnant without medical tests?

Do you want, but do not know how to determine if you are pregnant or not and you do not have the opportunity to purchase a medical test? Then this can be done using other methods, including folk. Many women prefer to seek help in a period of uncertainty with pregnancy precisely to the proven folk grandmother's methods. Therefore, we will reveal to you some secrets that will help you know that you are in a position without a test.

Of course, you can find out exactly about pregnancy without using a test after an appointment with a gynecologist, an ultrasound scan, or by taking daily body temperature measurements.

5 ways to find out if you are pregnant (without using a test):

Method 1 (Truthfulness 5: 5)

Take half a liter of warm water and dissolve a few potassium permanganate granules in it, until light pink in color. After that, add a small amount of your fresh morning urine there. Look, if the color of the resulting solution turns light yellow and lightens - the result is negative. If the color has not changed and small flakes have appeared, then you are 100% pregnant.

Method 2 (veracity also 5: 5)

Collect a small amount of morning urine in a clean container and add a few drops of iodine to it. Pregnancy will not be confirmed if it immediately spreads on the surface of the urine. And if the droplet lingered on the surface for some time, then your result is positive, you can start celebrating this good news.

Method 3 (degree of truthfulness 4: 5)

Prepare a white sheet of paper and wet it with your urine. After that, put a few drops of iodine on it. And watch out, if the color of the paper turns blue, then you are not pregnant. And if a bright purple or lilac shade appears, the result is positive. This method is one of the most reliable. Although there may be inaccuracies due to the different composition of the paper.

Method 4 - (truthfulness 3 of 5)

Collect morning urine in a clean bowl and pour wine into it, in a 1: 1 ratio. Then follow the result: if the resulting mixture remains light and transparent, the result will be negative. And if it turned cloudy and slightly changed its consistency, it became like cottage cheese - congratulations, you are a future mother.

In fact, the degree of truthfulness of this method is not high, due to not always high-quality inexpensive wine. It must be completely free of dyes and various chemical additives that affect the results of this test.

Method 5 (truthfulness 2: 5

Take your morning urine and place it in a container in which you bring it to a boil. Then pour it into a clear glass container. See if you are pregnant for flocculation in your urine.

This technique does not have a high level of truthfulness, because when boiling, the protein that is in the urine can simply curdle. As a result, it will be difficult for you to distinguish it from the resulting flakes.

A pregnancy test is a modern and simple way to find out about the onset of conception. There are many very different tests that differ from each other in the degree of accuracy and sensitivity. A woman should know what tests are, how they differ and how to make the test correctly.

How a pregnancy test works

Using the test is a convenient way to find out about pregnancy as early as possible. The reliability of the results obtained is approximately 98%. Pregnancy is determined by the interaction of the reagent on the test strip and hormones.

HCG is a hormone that is produced in the body almost immediately after conception. As the fetus grows, its amount in the urine increases.

It is enough to lower the strip into a container with urine, and the area with the substance is colored with the reagent - stripes appear on the light part.

What the strip shows

A pregnancy test will show a positive result if 2 strips appear. One of them always appears and almost immediately after the dough is dipped into the urine. It is painted in a bright blue-crimson tone.

The appearance of the second line is possible only if the hCG hormone is present in the urine, which is responsible for the onset of pregnancy. If conception has not occurred, only one strip will be visible on the test after a few minutes.

What a positive pregnancy test looks like

The result should show 2 straight lines. The intensity of the colors can vary significantly. In this case, the control strip responsible for the positive result may be paler.

What a negative pregnancy test looks like

If the result shows 1 single strip, this indicates the negativity of the test.... The same result is indicated by a weak color intensity of the second strip or its strong blur. The white color of the strip means that a lot of liquid got on it and it did not have time to react.

The pregnancy test has a 98% reliability of the results obtained.

Weak second strip on a pregnancy test - what does it mean

Such a reaction is possible with a short pregnancy period, or a negative pregnancy test. If the test is done before the delay, too little time has passed since conception. Doctors recommend in this case to do repeated tests after a while.

What are pregnancy tests - types of tests

The tests differ in appearance and sensitivity. Some allow you to find out about pregnancy a very short time after conception.

Test strips

Such tools allow for quick diagnostics.... They are very easy to use, decipher, cost up to 100 rubles. Such tests are a strip with a reactive substance, one end of it is placed in a container of urine. After 5 minutes, you can already see the result.

The appearance of a second line on a pregnancy test is possible only if the hCG hormone, which is responsible for the onset of pregnancy, is present in the urine.

Usually, when determining pregnancy in this way on the first day of delay, the result is 97% true. But even he can be wrong if you do not follow the recommendations for use.

To carry out the test, you need to take a clean container and collect urine in it - it is best to do this in the morning, when the hCG hormone reaches its maximum concentration. For half a minute, you must lower a strip into it.

A check bar will immediately appear to indicate that the test was performed correctly. After 5 minutes, a second streak may appear, which means a positive result.

The advantages of this type of test:

• affordable price;
• wide range of.

Disadvantages:

• low sensitivity;
• the need for a separate container for testing;
• with a strong concentration of urine, it may show erroneous results;
• with insufficient impregnation or, conversely, with strong immersion of the strip in a container with urine, it may give erroneous readings.

Inkjet pregnancy test

This type of testing belongs to the modern method of determining pregnancy and is considered more reliable. The tests are very different from previous generations of similar research methods.

Such tests have a complicated design and increased sensitivity. Thanks to this, they allow you to show reliable results even with a low level of hCG.

The test has a special layer. In the presence of hCG, the reagent reacts with the hormone and shows an accurate result. Already after 60 seconds, the test is ready to show valid data. The cost of such tests is much higher than that of other, less accurate, analogs.

Advantages:

• the possibility of using such a pregnancy test under any conditions;
• no need for a container for measurement;
• applicable at any time of the day.

Inkjet test cassettes have a more complex design. On their rod, which consists of tiny channels, urine reaches the test area with a reagent. This part contains a latex layer with antibodies that actively react to hCG.

Even at a very low concentration of the hormone, the reagent will show correct results. This way can be used from the first day of the delay in the menstrual cycle.

Electronic (digital) test

Such a test has a similar mechanism of operation as the others. He actively reacts to the presence of hCG. It can be carried out at any time of the day, regardless of the degree of urine concentration.

Capable of showing accurate information from the first day of the delay. The accuracy of the indicators is within 98%.

Despite the low cost, it is able to show the correct indicators within a few days after the onset of the intended conception. The closer the day of delay, the higher the percentage of reliability of the results.

According to the survey results, even if he showed a negative result before the day of the delay, then on the first day of the delay he could already show the onset of pregnancy.

It is recommended to repeat this test several times for greater confidence in the performance.... As soon as urine is absorbed into the reagent strip, the clock appears on the screen. This indicates the health of the device. After 3-4 minutes, the results are displayed on the screen with a plus or minus sign.

Tablet tests

Similar meters also are quite sensitive and are able to fix the onset of conception already in the early stages. To obtain the result, a drop of urine is applied to a special window with a reagent strip.

This type of dough is more modern and more expensive than conventional strips. It is often used for testing in medical clinics.

The kit includes a special pipette. After the urine reacts with the reagent, the result is displayed in the window. At the onset of conception, the reagent becomes colored. This type of definition of conception is the most reliable among analogues.

Advantages:

• no need for a special container;
• the presence of a pipette for analysis.

Disadvantages:

• difficulty collecting the required amount of urine;
• high cost in comparison with analogues.

Reservoir test

This test is equipped with a urine reservoir. There is a window on the front of the device, and the reagent area is built into the reservoir. In this case, the accuracy of the result is independent of the volume of urine. The reagent is capable of absorbing only the required amount to determine the likelihood of conception.

How many days after the delay in menstruation, the conception test can be done

Pregnancy test can be applied from the first day of delay... But many women have an irregular menstrual cycle and cannot correctly calculate the onset of this period. After the onset of conception, the woman's body begins to prepare for the upcoming gestation process.

Immediately, the restructuring of the entire hormonal system begins, the level of hCG rises many times. It is to him that all systems for determining pregnancy respond.

To confirm the result, at least 4 tests must be done, preferably with an interval of several hours at different urine concentrations.

Pregnancy can occur after the egg is released from the ovary - this period is called ovulation and takes place around the middle of the menstrual cycle. Thus, when calculating the probability of fertilization, 2 weeks after the last cycle and the release of the egg, conception is possible.

Implantation takes place for a few more days. The hCG hormone begins to be produced after the fetus is attached to the wall of the uterus. And every day its level increases.

Within a week, hCG reaches the level that can be determined by tests. This allows testing after the start of the anticipated delay.

Delay does not always indicate pregnancy, it can be caused by stress, hormonal disruption and the presence of chronic diseases.

Will the test show pregnancy before the delay?

Tests with good sensitivity are able to show the result even before the expected date of the next cycle. This is about 3 weeks after the previous last day of your period.

By that time, fertilization is already taking place and the level of the hormone produced is already capable of being displayed on hypersensitive tests.

When a pregnancy test shows an accurate result - how long will it take?

About 13 days after the end of menstruation, the egg can be released and fertilized. Another 3-4 days are given for the attachment of the embryo and the start of hormone production.

So already 3 weeks after the last menstruation, early pregnancy can be detected, about a week after conception.

Sensitivity of pregnancy tests

All tests to determine pregnancy indicate the minimum level of the hormone to which it is able to respond. It usually varies from 10 to 30. The lower the value, the more sensitive it has, which allows you to do tests as early as a week after the expected date of conception.

Online pregnancy test

Pregnancy cannot be diagnosed based on non-specific symptoms and doubtful signs that occur in the early stages (nausea, breast engorgement, etc.). Moreover, no online pregnancy test can reliably answer your question "Am I pregnant?"

An online pregnancy test is nothing more than a fortune-telling with a simple set of questions. Such online tests are based on the first signs of pregnancy, and the results of a pregnancy test are very indicative. And the absence or presence of any signs can not say about the presence of pregnancy, or about its absence. A pregnancy test is widely used to determine the exact presence of pregnancy.

If you have suspicions or doubts, then do not waste your time answering the questions of the online pregnancy test, because when there is a question about a possible pregnancy, regardless of what result a woman expects, positive or negative, she only hopes for reliable answer.
