Pregnancy test: how to choose the best

Perhaps every sexually active woman knows what a pregnancy test is. After all, it is to his help that we resort, if suddenly we understand that critical days do not start for a suspiciously long time. And then, with a sinking heart, we wait for the result, which the test will show to find out whether this pregnancy or delay is due to other reasons. About what the principle of the work of pregnancy tests and how much you can trust them we will tell in our today’s material.

To begin with, we want to introduce you to a hormone with a proud and unpronounceable name human chorionic gonadotropin it is released by the placenta during pregnancy, and is usually called abbreviated as hCG or simply a pregnancy hormone.

This amazing hormone begins to develop vigorously the female organism just when a fertilized egg is implanted in the uterus, that is, from the first hours of pregnancy. Every day his level rises, for example, by the fifth day of pregnancy he is from 25 to 50 mIU / ml., At the 4th week his level is already about 3000 mIU / ml. and above, and at 8 10 weeks it reaches a maximum of 200,000 -270000 mIU / mL. Impressive, right?

It is on presence in the urine or blood of this specific hormone and respond to pregnancy tests. Test producers ensure that pregnancy can be determined from the first day of the delay, but this statement is not always true. On early, up to 4-5 weeks, there is a high probability that the pregnancy test will show unreliable result because of an insufficient amount of the hormone hCG.


Submit a blood test for hCG during pregnancy will be needed several times, it tracks the state of pregnancy. Low rates of hCG in pregnant women can talk about pathology (ectopic pregnancy, fetal pathology, placental insufficiency, etc.), and high may be with multiple pregnancies or fetal pathologies.

Of course, if we look at the results of the test and are very much looking forward to (or do not expect, cases are different) coveted two stripes, it will be insulting if the test turns out to be erroneous. Test results can be false positive when the test shows that you are pregnant, but in fact it did not happen, and false negative when the test shows that you are not pregnant, and all the symptoms of pregnancy are present. Let's find out the main reasons why a pregnancy test can reveal untruthful information.

Too early. Doing a pregnancy test is better to adhere to the old wisdom that it is necessary to hurry up slowly, and remember that if the test is used too early, the result can be false-negative. Cause: the amount of hCG hormone in your urine is not yet enough to be diagnosed by this type of test.
