The essence of the method of diagnosing pregnancy is an express test.
The method is based on the fact that the presence of human chorionic hormone (hCG) in a healthy woman is produced only during pregnancy. It is produced by the hCG of the placenta, it can already be determined in the urine with a two-week pregnancy, usually it corresponds to the first day of delay or the day 2-3 hours before the expected menstruation.
The rules of the pregnancy test.
To make the test result more accurate, the following rules should be observed:
- it is best to conduct the test in the morning, immediately after waking up, collecting a small amount of urine (the morning urine is more concentrated, the amount of hCG is increased, and the results will be more reliable);
- if the test is performed at other times of the day, it is better to drink less liquid so as not to dilute the urine, which will lead to a decrease in the concentration of hCG;
- Urine for the test should be a little, about 20-30 milliliters;
- do not shake and shake the urine;
- urine should be at room temperature (do not freeze it or keep it in a cold place);
- the test is dropped into the urine to the level indicated on the test strip, the result is estimated within 5-10 minutes after its extraction;
- The container in which urine is collected must be clean.
Home tests: dignity.
Essential advantages of home pregnancy tests justify their overpriced:
- Ease of use;
- complete anonymity;
- early diagnosis of pregnancy;
- the accuracy of determining pregnancy to 95-100%.
Disadvantages.
Any methods of diagnosing pregnancy, including tests for determining in a home environment, have their disadvantages:
- tests may be substandard (with expiration date), there are quite expensive tests;
- tests can give false results;
- the presence of pregnancy does not confirm the fact that pregnancy is a uterine.
Why sometimes the test shows a false result.
It happens that the test gives a false positive or false negative result. This is influenced by the following factors:
- Too early testing;
- violation of storage of the test;
- non-compliance with the test;
- dysfunctional ovarian disorders;
- the test is performed after childbirth for 1-2 months (HCG does not completely disintegrate in the body);
- threat of abortion (there is a decrease in hCG);
- tumors, in which there is a synthesis of hCG (chorion carcinoma or bladder skidding).
Interpretation of test results.
It is very important to correctly interpret the results of the test, because the further actions of the woman depend on this:
- the test is negative, if only one line is visible on the test strip (it is recommended to repeat the test 2-3 days later);
- the test is positive in the presence of two pink (red) lines (if the delay is small, the second bar will show weakly);
- the absence of lines indicates the poor quality of the test, then it is better to buy another, another firm.
If the test is positive, you need to go to the gynecologist, who will confirm the pregnancy and prescribe a test. The used test should not be discarded, it is better to take it with you to a women's consultation to show the doctor.
What you need to pay attention to when buying a home test.
Not all tests are as good as they are praised, so make sure when buying:
- in the effective period of validity;
- in the integrity of the package;
- in the presence on the test package of explanatory instructions;
- in that test is the very company that you last used, and it did not fail you.
Do not neglect the test at home. Sometimes an early test will help to avoid various problems that occur when menstruation or pregnancy is delayed.
