Pregnancy test,

Pregnancy test, how does it work?

    Whether it is in the form of a stylet, card or strip, the pregnancy test contains antibodies to detect in the urine the presence of a hormone-specific pregnancy, chorionic gonadotropin or beta-hCG.

    This beta-hCG hormone is secreted by the cells of the fertilized egg to allow it to implant and remain fixed on the uterine wall at the time of implantation. She keeps the ovarian secretions so that the rules do not come back.
    
The amount of beta-hCG doubles every two to three days in the first six weeks of pregnancy and some of it is eliminated with urine.When to practice?

    
The beta-hCG hormone is detectable as early as 8 days after fertilization. Better to wait about ten days after fertilization or a few days after the presumed return of the rules (at least three). It is at this point that the hCG level is high enough in the urine to be detected.
    
Do it preferably in the morning when you wake up. Your urine is then more concentrated.

Which pregnancy test to choose and how to use it?

    
There are several kinds of pregnancy tests, pen-style, strips or cards. They are sold as boxes with all the necessary accessories and a very clear user manual. The best is to choose a simple model, no need to ruin with an ultra-technological test since all operate on the same principle.
    
For use, it all depends on the chosen pregnancy test pattern. The pen-shaped tests are placed directly under the urine stream, the strips or cards in a bottle of urine.
    
After a few minutes, the answer appears in the form of colored lines (a line: not pregnant, two lines: pregnant), symbols or in letters: "+++" or "pregnant" if the test is positive, " - "or" not pregnant "if the result is negative.
