If a woman has an abnormal and irregular menstrual cycle, her doctor will often recommend a Hormone 6 test to look at the specific ovarian endocrine situation, and for women who are infertile, a routine Hormone 6 test is also needed. The Hormone 6 test is actually very simple, and it is mainly done by taking venous blood from the laboratory. However, since the Hormone 6 test may be affected by diet or staying up late, you should not stay up late at night before the Hormone 6 test, and you should sit still for half an hour before the Hormone 6 test, and you also need to take blood on an absolutely empty stomach. This is because after eating, the secretion of hormones is often affected, resulting in inaccurate test results. Especially for women with irregular menstrual cycles, it is often recommended to have blood drawn on the second or third day of menstruation to check the basal endocrine condition of the ovaries, or if the blood is drawn during a non-menstrual period, then the specific period needs to be projected. It depends on whether it is in the follicular phase, or the ovulatory phase, or the luteal phase, because the reference values of the six hormones can vary greatly from one period to another, and the significance of their examination can also be very different. If the basal endocrine status is checked, it is often possible to confirm whether there is premature ovarian failure or polycystic ovary syndrome, and it is also possible to see whether one is in menopause.
