Currently, using a simple home test, you can determine not only the presence of pregnancy, but also a favorable period for conception of the child. The most common tests are the determination of ovulation by urine. A positive test for ovulation indicates an increased level of luteinizing hormone, which helps rupture the mature follicle and release the egg. The concentration of the hormone rises several hours before the onset of ovulation.
Conducting the test can show the following results:
- a weak strip on the test for ovulation indicates the absence of ovulation;
- two strips on the test for ovulation are an indicator of an elevated level of the hormone, that is, ovulation should occur within 12-48 hours;
- the absence of a strip means that the test is not suitable.
How to conduct testing?
Testing should be done daily at the same time strictly according to the instructions. The reliability of the test for ovulation is increased if abstained 2-4 hours before its use. The best time for the test is from 12 pm to 8 pm.
A false positive or weakly positive test for ovulation can be obtained if, on the days of testing:
- take plenty of fluids;
- do a test for the first morning portion of urine.
It is worth noting that the darker the strip, the greater the level of the hormone in the urine. If you receive a positive result, it is recommended that you have sexual intercourse within 24 hours after the test. This period is most favorable for conception .
In addition to the home test, there is a definition of the level of the hormone for the analysis of blood or the crystallization of saliva. These studies are conducted in the laboratory and are considered the most accurate. Such methods are recommended for women who can not get pregnant with more accessible methods.
