For many people, the conception of a baby is a pre-planned event, which is awaited with impatience. Then the two cherished stripes bring only happiness and anticipation of the birth of a new life. But it also happens that pregnancy can be undesirable. In this case, it is very important to know about your condition in time to make the appropriate decision.
The simplest way to find out whether a woman is in a position or not is a pregnancy test, which is an extremely simple and convenient biochemical system that determines the state of pregnancy even before a woman visits a gynecologist.
How does the pregnancy test work?
The effect of the test system is based on determining the presence in the urine of the human hormone chorionic gonadotropin . This hormone can be found in the urine only after the onset of pregnancy. Sometimes hCG can be detected in urine and in non-pregnant women, which indicates a serious illness.
The tests contain certain indicators linking HCH and changing their color if the concentration of the hormone becomes higher than the critical value.
What does a pregnancy test look like?
There are tests in the form of: test strips, test-cassettes, tests-medstrom. For each type of pregnancy tests, there is a manual, which should be clearly adhered to during testing.
How to pass a pregnancy test?
To make a test for pregnancy test strips, you need:
- Collect the urine in a special container and lower the strip to the level indicated by the arrows.
- Put the strip on a clean surface.
To determine pregnancy using test cassettes, you need to:
- Collect urine in a glass.
- Pour four drops of urine into the cassette window.
The application of the pregnancy test in the form of a jet system (test midstream) is as follows: taking the test, you need to remove the cap and place it under a stream of urine. Then the test should be closed with a cap and put on a flat surface. In any kind of test, the result is estimated after one to five minutes.
How to read a pregnancy test?
The results of any test, regardless of its type, are presented in the form of one or two strips. One strip of pregnancy test means no pregnancy.
2 pregnancy test stripes mean that the egg is fertilized and pregnancy has occurred. Even if the second band showed very little, it indicates a pregnancy.
When can I apply a pregnancy test?
Human chorionic gonadotropin appears in the body of a woman, and therefore can be determined by a test, only on the seventh-tenth day after the embryo is implanted into the uterus. Therefore, whether pregnancy has come or not, it is impossible to find out immediately after sexual intercourse. For this, you need to wait seven days. It should also be taken into account that the level of hCG in the body increases not immediately, but gradually, so at very early stages of pregnancy, it can give a false-negative test due to the still insufficient content of this hormone in the urine.
The most sensitive are jet tests that determine pregnancy several days before the date of the onset of menstruation. The remaining types of tests are best used only after the delay of critical days.
Every woman should understand that maintaining a sexual life even with a high degree of protection can lead to pregnancy. If the menstruation is delayed for several days - this is quite normal. Do not be too early to rejoice or to despair on this occasion. If a woman has doubts about the reliability of the test, then it is better to do it again, but after a few days.
