Couples that plan the conception of a child often use tests to determine the ovulatory period. How does a modern ovulation test work and how to use it correctly?
A variety of ovulation tests: what to choose?
The ovulation test is a strip with an indicator on one side that responds to an increase in luteinizing hormone (LH) in the urine. The surge of this hormone occurs when the level of estrogen is at the peak and the follicle is ready to ovulate. Thus, a woman can determine a favorable moment for fertilization of the egg.
To test, a small portion of female urine or saliva is required. During the day or two before ovulation, the maximum number of LH is determined in this biomaterial, which ensures the reliability of this test.
The pharmacy meets many varieties of such a test. The principle of action they have one, but the accuracy of the results and the convenience of operation are different.
You can purchase one of these ovulation tests to the choice:
- Test strips are the easiest test in the form of a thin strip with a reagent at one end. To get the result, you need to lower the end with the indicator in the urine and wait 3 minutes. These tests are cheap, but less sensitive.
- Test tablets - reliable, accurate, but dear test of tests. Outwardly, they resemble a plastic case with a small window. It is for him that I need to drop urine and soon you will learn the result.
- Inkjet test is the most reliable test. It must be immersed in the urine or direct under its jet.
- Electronic test - the device is intended to identify LH in saliva. A drop of saliva is placed in the window and drawing appears on the screen. After comparing it with a sign, the hormone level is determined.
How is the test for ovulation
The ovulation test must be carried out twice a day for 5-7 days. This is required because the emission of LH can occur at any time of the day and the peak of the concentration is held in the urine of less than 24 hours. Therefore, it is better to spend such a test several times a day in order not to miss this important point.
When should I do this test? Doctors recommend starting to monitor 17 days before the alleged start of menstruation. If the cycle is 26 days, the test is made from 9 days of the menstrual cycle.
Below is a simple table with suitable days for testing.
Testing should be repeated until the result confirm the emission of LH. Unfortunately, such a method for determining ovulation is not suitable for women with unstable menstruation and hormonal disorders.
What you need to remember, making a ovulation test
- It is necessary to do the test through the same segments of time, for example, every 12 hours.
- The optimal time for the test - from 10 00 to 20 00.
- For the dough does not fit the first morning urine.
- If you want to use such a test, stop receiving hormones that affect the LH.
- 1.5-4 hours before the test, reduce the amount of liquid consumed.
- 2-3 hours before the test, refrain from trips to the toilet.
If you lose such nuances, there is a high probability that the test will give an erroneous option.
The ovulation test greatly simplifies the process of conception, especially if there are certain problems with it. But do not forget that the tests are often mistaken, and it does not hurt to use such additional methods for determining ovulation, as a graph of basal temperature and ultrasound.
