Incontournable when it is suspected a pregnancy, the pregnancy test, if it is known by all women (he sold 25 million each year in France), still remains a tool in the somewhat mysterious workings for many of us…
How does it work?
Pregnancy tests all work on the same principle: they detect the presence in your urinalysis of a hormone secreted during pregnancy, the β-hCG (Chorionique gonadotropin hormone).
To do this, place the absorbent stem of the test under the jet of urine during a period of 10 seconds.
It is best to take a pregnancy test in the morning, because scientists have shown that the rate of β-hCG was much higher at this time of the day (urinalysis are also more concentrated). This will provide you with a more reliable result.
Is the result reliable?
Provided you follow professional instructions, pregnancy tests are reliable about 99%!The probability that your test shows a ” “false positive ” (result indicating a pregnancy while in reality no pregnancy began) is extremely low. On the other hand, the ” “false negative ” (negative test while you are indeed pregnant) can sometimes happen. Typically, it is misuse of the test (done too early or not respect the operating instructions) which resulted in this type of mistake.
How to read the result?
Most of the pregnancy tests of trade there are two windows.
- The first is called control window;a pattern appears there after use, it is proof that the test has worked well.
- The second is the playback window that gives you the result of the test. According to the tests (see the manual), a pattern must appear in this window if you are pregnant: it is often a line, or a cross. Depending on the time of your cycle where you perform the test, the colour of the feature (s) can be more or less dark: it is not important, only account for the fact that a line appears!
If your test is positive, congratulations! Contact your doctor or your Gynecologist so that it eventually prescribe you blood taken allowing to date more precisely the beginning of your pregnancy.
If the test is negative, but you still have strong suspicions, pass a few days and try again. If your doubts, contact your doctor or gynecologist.
