• The reagent of such a test is applied to paper, and the accuracy of its concentration may suffer, which makes the test strips considered the least reliable

. The tablet tests have a higher responsivenesson the level of hCG, which in individual brands reaches 10 mMe. This is a test strip, which is placed in a special plastic tablet with 2 slits.

IMPORTANT: To obtain a reliable result, use two or more tests for pregnancy.

When to do a pregnancy test after conception?

The sensitivity of the test is measured in international units per ml( mMe / ml).The average responsiveness of the tests is 20-25 mMe / ml. The lower this figure, the sooner after conception it is possible to diagnose pregnancy.

So, the highest response has instruments with a mark of 10 mMe / ml. With the help of them you can learn about pregnancy already on the 7th day after conception, if the day of conception, of course, you know. At the same stage, clinical analysis for the diagnosis of fertilization is also being submitted.

IMPORTANT: No home appliance will show you the length of the pregnancy. All tests are aimed only at determining whether a conception has occurred or not.

Test strips, the sensitivity of which reaches 20-25 mMe / ml, will show the correct result only 10-14 days after conception.

From which day of the delay, the pregnancy test can be done?

Even if you know the exact day of conception, it is best to conduct a home diagnostic procedure from the moment of delay.

Why is not there a single strip on the pregnancy test?

• A test strip is a piece of paper impregnated with a special substance that, upon contact with the urine, shows one or two pink, sometimes red, features of the
• . Anyway, without fail, you will see the first pink line. It appears, usually after half a minute after contact with the urine and means that the test is not defective and is suitable for diagnosing
• . The second line appears about 3 minutes later and indicates the successful fertilization of the ovule

. The pregnancy test should have a control strip even ifyou are not pregnant

• The expiration date of the device has expired. Check on the package to what date this particular test is valid. If it is really overdue, purchase a new copy and repeat the procedure
• The defective test. This happens infrequently, but it is still possible. To be safe, buy in the drugstore strips of another company and repeat the procedure
• You have incorrectly performed the diagnostic session. The test can give a negative answer or show nothing at all if you hold the strip in the container too little or too long

• A fairly common situation when the device is mistaken is its expired shelf life or marriage. If the test is damaged, initially defective or overdue, you may well see the second strip, even if not pregnant. That's why physicians recommend to carry out 2 or 3 procedures at once to make sure of the result of
• . Often, women are so expecting to see a positive result, that a weak hint of a second strip is taken for a certificate of pregnancy. If the procedure is performed correctly, the second strip should appear rather clearly
• It turns out that the level of hCG can increase not only due to the embryo attachment to the uterus. It can also increase because of a cyst or a tumor in the body. However, a test that records an increase in hCG levels does not determine the cause of this and produces 2 strips on the device. Interestingly, even in men, the test can show a false pregnancy if the level of their hCG is increased due to a tumor
• Today, hormonal drugs known as hCG are known. They are taken from infertility. During the period of taking these medications, the test can also diagnose fertilization, even if it did not actually happen.

Under different circumstances, a pregnancy test can show a false fertilization.

• . As a rule, girls and women choose the most affordable option - test strips for primary pregnancy determination. However, their accuracy leaves much to be desired. Many consumers complain about false results or the absence of any strips, which indicates the inapplicability of this device to diagnose pregnancy
• The most accurate available means are jet pregnancy tests. The most accurate - digital. After all, the electronic device can be used as many times as necessary and be sure of the result it will show
