The female hormone 6 test is usually done on the 2nd-4th day after the onset of menstruation. However, women with infertility, amenorrhea or long-term absence of menstruation can be tested at any time. The main purpose of the sex hormone 6 test is to understand female endocrine function by measuring hormone levels and to diagnose diseases related to endocrine disorders, such as menstrual disorders or menstrual disorders. The value of female hormone 6 will change according to the change of physiological period. Usually the luteal body degenerates during women’s menstruation, and the level of estrogen and progesterone in the blood drops significantly. On the other hand, the 2nd-4th day after menstruation, which is the early follicular period, hormone levels are more stable and can better reflect the functional status of the ovaries. However, for those who do not have menstrual periods for a long time and are eager to know the test results, they can be checked at any time. In addition, it is recommended to have a blood test in the morning on an empty stomach, and not to eat after 10 pm the night before the test to ensure sufficient sleep to avoid affecting the test results.
