What should we pay attention to when doing the six-item estrogen test?

Estrogen is an important indicator for female friends, especially for those who want to have children. Once any problem occurs in the six estrogen items, it will cause abnormalities. Female friends who have been infertile for a long time need to have these items checked. Generally, blood tests for endocrine system, etc. are done 3-5 days after the onset of menstruation, and the results will be more accurate.

1. Inspection time

The best time to check endocrine system is 3-5 days after menstruation. This period belongs to the early follicular stage and can reflect the functional status of the ovaries. However, for those who have not had their menstruation for a long time and are eager to know the test results, they can have the test at any time. The time will be taken as the time before menstruation, and the results will refer to the test results of the luteal phase.

The most accurate result is obtained by having a fasting blood test at 9 a.m. on the 3rd to 5th day after the onset of menstruation. For those who are infertile or have amenorrhea, or have not had menstruation for a long time, the examination can be done at any time, but it is best to do it on an empty stomach.

As long as men do not do strenuous exercise and lead a regular life, they can check at any time on an empty stomach between 8 and 11 a.m.

2. Indications for the six estrogen tests

Women who experience menstrual cycle disorders, amenorrhea, abnormal genital bleeding, gynecological tumors, etc. need to undergo routine sex hormone tests.

In men, if there are semen abnormalities, impotence, hormone-related tumors, etc., six sex hormone tests are required.

The content of sex hormone examination is the same for men and women.

3. Six estrogen test methods

The inspection items are different and the attention methods are also different. The inspection content can be a full check or a single item check.

1. To check estrogen, progesterone, and follicle-stimulating hormone, 2 ml of each is required after venous serum separation.

2. To check testosterone, 2 ml of venous serum is drawn. The commonly used method is radioimmunoassay, which can be measured after the serum is separated.

3. Prolactin should be checked on an empty stomach, with serum drawn around 9 a.m.

4. Check luteinizing hormone. Although it is also a radioimmunoassay test, because luteinizing hormone is secreted in a pulsed manner, it is best to collect samples 3-4 times within 1 hour and then mix them together for measurement, which is more accurate.
