You can do the test before your period is delayed. When can I do a pregnancy test. When can a pregnancy test be done before a delay

If a woman suspects that recent sexual intercourse has ended in conception, she will not calm down until she finds out whether her premonitions are justified.

If it were possible, she would not refuse to find out about it the very next day after the act, so that she would have time to reflect, be nervous or be happy.

To the delight of such impatient ladies, today you can take a pregnancy test before your period is delayed, which means you can find out about your interesting situation at the earliest possible date.

Today, pregnancy tests have become such a common household item that women who use them somehow do not think about their mechanism of action. Without knowing the principle of their work, it is difficult to understand whether it is possible to do the test before the delay in menstruation.

Pregnancy recognition by express tests occurs by detecting in the urine of the expectant mother a special substance called hCG (human chorionic gonadotropin). Despite the fact that this substance is often called the "pregnancy hormone", it is present not only in the female, but also in the male body at a concentration of about 5 mIU / ml. After 1-2 weeks after fertilization, hCG begins to be actively secreted by the chorion, and its level rises 5-20 times from the initial one. At this very time, it is found in urine, to which modern highly sensitive tests react.

How the test works

According to the analyzer type, the test results are shown as bright stripes or digital data. Today women use these types of tests:

• electronic (digital) - the most sensitive type, as a rule, for repeated use, some of the varieties are able to determine even the gestational age, the result appears in the window in the form of words or plus / minus;
• jet - these are slightly less sensitive analyzers that work directly during urination, without requiring the use of containers for urine;
• tablet - plastic tests with a window for applying a few drops of urine;
• strip tests - the simplest analyzers in the form of strips with an indicator substance applied to them, the result appears in the form of red stripes: one means “no”, two strips - “yes”, pregnancy has come.

Before using this test, a woman will need to find a container for urine to dip the strip into.

The testing process usually takes about 7-10 seconds to contact the urine with the indicator and 3-5-10 minutes to visualize the results. Each type of device has its own terms, which are usually indicated on the package or insert for the test.

You can take a pregnancy test at any time of the day, as stated in the instructions for using the devices. It is known that the highest concentration of hCG is observed in morning urine, so doctors recommend taking a pregnancy test in the morning, especially if done, before the delay in menstruation.

Will pregnancy show before delay?

Modern ultrasensitive analyzers with a sensitivity threshold of 10 mIU / ml are capable of detecting hCG at the earliest possible date. If the test is carried out before the delay (about 2-4 days before the expected onset of menstruation), it will certainly show pregnancy, if it has come.

If the question of whether the test will show pregnancy before the delay is no longer in doubt, the accuracy of its results is still not enough to determine pregnancy. Due to various circumstances, even an electronic test, which is considered the most accurate, can be mistaken. Rather, it is not the tester itself that is mistaken, but the body, releasing hCG into the urine and causing a false-positive reaction of the indicator. This happens when:

• the woman's use of medications containing chorionic gonadotropin;
• recently suffered artificial termination of pregnancy;
• the presence of tumor processes in the female body.

In addition to false positives, false negative test reactions are also possible (when there is a pregnancy, but the device does not detect it).

The reasons for this result are:

• cardiovascular and renal pathologies that prevent the full release of hCG into the urine;
• Excessive drinking of water or diuretics shortly before testing;
• taking the test too early (especially if the cycle is irregular).

To avoid mistakes, all possible provoking factors that affect the concentration of hCG in urine should be excluded.

Confidence level

In the annotations for pregnancy tests, rather high figures for the reliability of the analysis are presented. According to these data, modern electronic tests have the highest possible degree of reliability - from 99%, if the samples are carried out in a timely manner, correctly and in accordance with the instructions.

When determining the duration of pregnancy, the reliability of tests, especially those carried out before the delay of menstruation, is lower and is 92%.

4 most sensitive analyzers

Based on consumer surveys and clinical observations, devices of several brands were included in the rating of the most sensitive tests:

1. Clearbleu DIGITAL - one of the most expensive digital tests with a sensitivity level of 10 mIU / ml and a claimed reliability of more than 99%;
2. Evitest proof - cassette (flatbed) test with a high level of sensitivity and reliability;
3. Frautest planning - a set of tests for ovulation and pregnancy detection with disposable containers for collecting urine for each test;
4. Frautest express ultrasensitive is an inexpensive strip test with a sensitivity level of 15 mIU / ml.

Even when using the most highly sensitive pregnancy test, you should not rely on its 100% reliability, since under some circumstances erroneous results are possible.

Unconditionally, pregnancy can be determined by instrumental research methods (ultrasound), which should be done after passing the test.

Earliest test that can be done

If a woman is looking for the earliest pregnancy test that can show results before the delay in her period, she should pay attention to Biocard HCG. Fast response times and ease of use have made this cassette test popular among similar analyzers. The sensitivity of the device is indicated by the fact that in most reviews the ability of this test to determine pregnancy before the delay of menstruation is noted.

One of the most high-tech and highly sensitive tests that can "see" pregnancy in the early stages (before the delay in menstruation). In addition to stating the fact of pregnancy, this digital test "knows how" to calculate the gestational age (again, by the amount of gonadotropin in the urine).

Incorrect interpretation of data when using Cliable digital is excluded, since the result is assessed not by stripes, but by absolutely unambiguous signs: + or - (plus or minus). The gestational age is indicated something like this: 2+, which means more than 2 weeks of pregnancy. If this function is not of interest to a woman, you can choose a less expensive, but equally effective test from the same line without the option of calculating the term.

Positive result

If the test results are positive, the woman can theoretically be congratulated. But in fact, she still has a lot of work to do to safely endure and give birth to a healthy baby.

First, you should visit a gynecologist and register. You should not postpone this important matter until later, since an early examination allows you to identify and eliminate possible problems with greater success than if it is done in a critical situation (for example, at). And the very fact of a positive result should be confirmed by ultrasound in order to more reliably determine the duration of pregnancy and calculate the date of birth, taking into account the delay in menstruation.

Finally, get valuable guidance from a gynecologist who will "guide" the pregnancy for the remaining 7-8 months, preferably in the early stages.

If a positive result turned out to be an undesirable event, a woman should all the more visit a doctor, think over everything and make the right decision, perhaps the most important thing in her life.

Conclusion

1. , regardless of their varieties, work according to the same principle of action - they react to hCG, which rises in the urine of a pregnant woman.
2. If the sensitivity of the test is 10 mIU / ml, it can recognize pregnancy before the period is delayed.
3. Despite the claimed reliability (99%), pregnancy tests can produce both false positive and false negative data.

In contact with

Many representatives of the fair sex are familiar with that exciting feeling of agonizing expectation, when the whole future life depends on a few minutes. Desired, and even more so long-awaited pregnancy opens up new horizons and fills every moment with meaning. There are many hopes and disappointments associated with pregnancy tests. But, recklessly trusting their results is not worth it.

Pregnancy tests are sold at any pharmacy. If necessary, you can seek advice from a pharmacist or local gynecologist. It is easy to carry out an express test, it is enough to carefully read the instructions before use.

After the embryo is implanted into the wall of the uterus, increased hormone production begins in the female body. The tests have a special indicator that reacts to the presence of this hormone in a woman's urine.

It is thanks to the increased human chorionic gonadotropin that the test shows the cherished two strips. If pregnancy has not occurred, then a low level of hCG during a home test will not be recorded.

For the results to be more reliable, it is necessary to select tests with high sensitivity (10-20 mIU / ml). Such tests can show pregnancy before your period is delayed.

What to look for when buying a pregnancy test

1. The appearance of the package and its integrity. Wrinkled and torn packaging is a reason to refuse a purchase.
2. Detailed and understandable instructions.
3. Date of issue and expiry date. They must be clearly stated and not in doubt.
4. Well-known and time-tested manufacturers are a guarantee of the quality and high accuracy of these products.
5. Place of purchase. A pharmacy is the most suitable place to purchase a pregnancy test. Products that are sold through pharmacy chains regularly pass all the necessary checks and have the appropriate quality certificates. In addition, pharmacists observe optimal storage conditions and monitor the timing of the sale of medicines.

Benefits of tests

• a wide range of prices - you can choose high-quality and inexpensive products from various companies;
• ease of use - the test does not require any special conditions or skills. The main thing is to follow the instructions carefully;
• fairly high accuracy (from 90 to 100%);
• early pregnancy diagnosis. It is possible to conduct the test several days before the expected delay.

Disadvantages of a pre-delay pregnancy test

1. The fact of pregnancy, unfortunately, does not always mean that it is developing correctly. In some cases, the fertilized egg is absent in the uterus, and the fertilized egg, for various reasons, remains in the fallopian tube. Naturally, in such conditions, the further course of pregnancy is impossible. To exclude such suspicions, ultrasound diagnostics are performed.
2. False results. Poor quality tests can show negative results before delay. In addition, the level of hCG in the urine may be insufficient. In such cases, it is recommended to repeat the test after a few days.
3. The most reliable and easy-to-use tests are quite expensive. Therefore, not every woman can afford to purchase such a product, especially if several such tests may be needed for early diagnosis of pregnancy.

Reasons for false positive test results

• Treatment of various gynecological diseases with hormonal drugs. In such cases, the appearance of a second ghost strip on the test is also possible.
• A pregnancy that's over. There are often cases when, even a couple of months after an unsuccessful pregnancy, the test shows two stripes. This phenomenon is quite possible, because the level of hCG in a woman's body is still quite high.
• Tumor masses are another reason for a possible false positive result. The production of the hormone gonadotropin occurs in sufficient quantities, but the tumor produces it, therefore, in any case, it is better to consult a doctor for examination and diagnosis.
• Incorrect use of the test - the instructions describe in detail all the manipulations and clearly limit the time allotted to obtain the most reliable result. Therefore, if, for example, the test is overexposed in a container with urine, then the test may be unreliable.

Varieties of tests

1. Inkjet... Convenient to use and highly sensitive. Such tests, even before delay, can show pregnancy. A reliable result is guaranteed at any time of the day or night. It is enough to substitute such a test under a stream of urine and wait a few seconds. The most popular firms in this category are Duet and. The only drawback of such tests is the price, which is not available to everyone.
2. Tablet. A few drops of urine are placed in a special hole using a disposable pipette. The result appears in another window. These tests are often used in hospital settings because they are the most informative and accurate. One of the most highly sensitive tests is Sezam. This test can also be performed before the delay, it is able to establish pregnancy as early as a week after fertilization. Of course, its price is high.
3. Test strips... A wide assortment and affordable price are the main advantages of such tests. However, before immersing the test strip in a container of urine for a few seconds. The container for urine must be sterile. The most popular and reliable tests are Ultra, Frautest and Evitest.

Pregnancy test before the delay of menstruation: doing it right

As a rule, the highest concentration of hCG is found in morning urine, so the result will be most reliable in the morning. As for the tests with high sensitivity (10 mIU / ml), they can be used at any time.

The day before the test, a woman needs to pay attention to the amount of fluid consumed and, if necessary, reduce its volume. The fact is that due to frequent urination, the concentration of hCG can sharply decrease and provoke a false-negative test response.

First of all, a woman will need a small sterile container for urine. It is worth taking care of this in advance and preparing everything you need in the evening. There are special windows in tablet and inkjet tests, so there is no need to buy a separate container.

The test must be removed from the packaging immediately before use.

It is enough to dip the test strip in a container of urine for just a few seconds, then place it on a flat surface and evaluate the result according to the instructions. Usually, two stripes indicate a positive result, and one indicates no pregnancy.

If you have a delay in your period and you suspect you are pregnant, then the easiest and fastest way to check your guess at home is to do a test. Modern tests are fairly accurate, completely accessible, and very easy to use.

But what if the expected start of menstruation is still far away, and doubts about the likely pregnancy are creeping in now? Will it be correct, carried out even before the onset of the delay in menstruation?

When does the test show pregnancy?

Modern pregnancy tests are highly reliable and sensitive. Regardless of the quality and the manufacturer, they all work according to the same principle. The test contains a special substance that reacts to the presence of the hormone gonadotropin in a woman's urine. Human chorionic gonadotropin (hCG) is secreted by the chorion (the forming placenta), that is, in the absence of pregnancy, it is practically absent in the blood (with the exception of some factors: illness, taking hormonal drugs.

Gonadotropin begins to be released immediately after the embryo is introduced into the uterine wall, which occurs no earlier than 7-10 days after fertilization. But at this time, its level is just beginning to rise. Every two days the concentration of gonadotropin doubles and after a certain time reaches the level when the test is able to "see" it. This moment is determining the timing of the appropriate test. It is for this reason that doctors, pharmacists, and everyone who is familiar with the principle of the tests, recommend testing no earlier than on the third day of the delay in menstruation. It is believed that the previously performed procedure is not reliable due to the too low content of hCG. But if you really can't stand it, pharmacies sell highly sensitive tests (as a rule, these are) that recognize gonadotropin in low concentrations and allow their use even before the start of the expected period. How it works?

Will the pregnancy test show before the delay?

If the conception has taken place and the woman is pregnant, then the level of the hCG hormone in her blood begins to actively increase and by the first day of the expected menstrual cycle it usually already exceeds 100 mIU / ml. The concentration of gonadotropin in urine, which is used as a test fluid when a pharmacy pregnancy test is performed, is at a level half that in the blood, that is, by the expected day of the onset of menstruation, it is about 50 mIU / ml. Modern highly sensitive tests are able to identify gonadotropin at a concentration of 10-20 mIU / ml. Consequently, they can be carried out much earlier than the delay occurs. In this case, it is necessary to pay attention to the sensitivity of the test - this information is indicated in the instructions or directly on the package.

However, it should be understood that the reliability of a test carried out in advance will not be high enough, more precisely, the likelihood of receiving false results when testing before the delay in menstruation is quite high.

And therefore, whenever a pregnancy test is carried out - before a delay in menstruation or after - for maximum accuracy of its results, it is necessary to repeat the procedure after a few days (or even better, do it repeatedly). And be sure to be examined by a gynecologist if your period does not come. Often, the cause of delayed menstruation can be gynecological or infectious diseases of the reproductive system.

From the guest

I do not understand women who do the test BEFORE the delay. Why is this? I always do it only with a delay of more than a week, because I understand that everyone has failures. We're not robots! I think that only mothers are capable of doing tests before the delay, and an intelligent adequate woman will wait with patience.

From the guest

Girls, I did the test 10 days before the monsters, showed // strips) the tests were the simplest and cheapest)))

From the guest

Hello everyone ...)) for the first child, the test was negative by 4.5 months ...

Does it make sense to do a pregnancy test before the delay? In order to understand this, you need to know how tests work in general and what affects the result.

Let's say right away that now such a preliminary diagnosis of pregnancy is already quite possible, tests that can recognize pregnancy so early exist and work, but to believe them or not is another question.

With the birth of a new life in the mother's body, another source of hormones appears - this is the embryo. Its future placenta, chorion, secretes chorionic gonadotropin, a hormone that can only be present in the blood of a pregnant woman. This hormone is excreted in the urine, and all pregnancy tests work on its detection.

The accuracy of pregnancy tests approaches the accuracy of laboratory tests, but the sensitivity varies from test to test.

For example, test strips respond only to a hCG level of more than 20-25 IU, and they are able to recognize it when the hCG level does not exceed 10 IU. And such sensitive tests are suitable for preliminary diagnosis of pregnancy.

These pre-delay pregnancy tests may not work because your pregnancy is very short. Ovulation can occur a few days later than usual, and then the baby's chorion before the period of menstruation will still produce too little hormones, and you will receive.

The pregnancy test will show before the delay only if the embryo implantation has already begun, and the chorion is formed. This is not the case for the entire first week after conception, and only about a week before menstruation, the process of formation of the placenta begins and hCG appears in the blood, and the first days of it are still too small for any test. Despite the possible, the test will still be negative.

When planning a pregnancy, a woman looks forward to the confirmation of her hopes. Each cycle, she looks for symptoms and tries to feel the signs of conception. You can find out about pregnancy before the onset of menstruation using an express test. Does it really allow you to determine your position a week before your period?

As a rule, the very first sign in the onset of pregnancy is a delay in menstruation. Many girls do not want to wait for the cherished moment and are in a hurry to do a pregnancy test a week before menstruation. Observation of the fusion of a sperm and an egg is by definition impossible. However, computer reconstruction allows us to understand what exactly affects the performance of tests.

The reagent applied to thick paper can recognize the embryonic hormone hCG. If it is not enough in the woman's urine, then the diagnosis will not give a result.

Pregnancy occurs at the time of ovulation, which occurs around the 14th day of your monthly cycle. Conception itself does not happen immediately after the act of intercourse - it takes about a week for the egg to penetrate into the wall of the uterus, and about 3 more days for hCG to grow to a sufficiently high level.

Many are worried about how many days before menstruation the test will show pregnancy. It makes no sense to do it earlier than 4 days before menstruation. However, no one forbids experimenting and checking the result. If the cycle is irregular or longer than usual, then ovulation occurs later. The tests will be effective 14 days after intercourse. That is, with a cycle of 30-36 days, 5 days before menstruation, the test will show pregnancy.

A week before menstruation, the test can show pregnancy, or rather, two cherished stripes. They can not always be regarded as a positive sign, sometimes the test reacts to a woman's medication or disease. Sometimes hCG is found in the body of a woman who is not expecting a child. This happens when:

• a woman is taking a medicine containing this hormone;
• recently had an abortion;
• some time ago there was a miscarriage;
• ectopic pregnancy;
• incorrect execution of test instructions.

To confirm expectations, you can measure basal temperature in the morning. If it is close to 37 degrees, then conception can be considered successful. If the test shows a second fuzzy line, it is advisable to repeat the test after one or two days.

The instructions for most pregnancy tests clearly state that it is not wise to use them before your period. They must be performed when menstruation has not come. Whether the test can show pregnancy before menstruation depends on many factors, including the moment of fertilization.

If you don't feel like waiting, just get a test at the pharmacy. For an average test, a content of 25 mMU / mol of homone in your urine is required. However, for early detection of pregnancy, hypersensitive novelties have begun to appear in recent years. Such pregnancy tests help to find out the result before menstruation, even if the hCG level reaches 10 mIU / mol.

Accuracy of the results of various pregnancy tests before menstruation

When choosing a test before a delay in menstruation, it is best to contact trusted manufacturers. These tools include:

1. Frautest express. The test has a sensitivity of 15 mMU / mol. Manufacturers recommend using it two days before your period. It belongs to the category of ultra sensitive tests, it guarantees a fast and 99% correct result. It is effective at any time of the day, however, it is in the morning that the concentration of the hCG hormone is at its highest. The strip is immersed in a container of urine for 10 seconds and shows the result after 3 minutes.
2. Evitest. A pregnancy test is intended for early diagnosis, allows you to determine the result the day before menstruation. It is necessary to confirm the result after two days by repeated "Evitest". This is because the hCG level doubles every 48 hours. The test is similar to the first option.
3. "Mom Test". Possesses high sensitivity and guarantees the result already 2 days before the date of the beginning of menstruation. The sensitivity ranges from 10 mMU / mol. It can be used for diagnostics at any time of the day. Place the strip under the stream of urine or dip it into a container for 5 seconds. The accuracy of the German product is over 99%.
4. "Premium diagnostics". It detects the amount of hCG to urine at a concentration of 10 mMU / mol. This is the "earliest" test of all presented - it allows you to get the result already on the seventh day after intercourse. Does not require morning time, allows you to take an analysis at any time of the day. Place the strip under the stream of urine for 5 seconds, then close the cap for 5 minutes. Two stripes indicate successful fertilization.
5. "BB-test". The highly sensitive system diagnoses pregnancy at a hCG concentration of 10 mIU / mol. The manufacturers claim that their product only detects hCG, ignoring other female hormones. This allows you to give the most objective picture and reduce the level of false results. The use of the test is similar to the other examples given.
6. "Test for Best". A highly sensitive product helps to get results 7-11 days after intercourse. It is used by both women and doctors for their work. A positive result in the form of two stripes should be visible within 40 seconds after the strip is immersed in the urine.

Output

Thus, modern hypersensitive drugs allow a woman to know about successful fertilization a few days before the delay. To confirm hopes, it is necessary to measure basal pressure and visit a gynecologist.
