For women with regular menstruation, they can go to the hospital on an empty stomach on the 2nd-3rd day after their menstruation to have their blood drawn for the test; for women with irregular menstruation, they can have the test at any time. Sex Hormone Six test is mainly to check the female endocrine function, the test items include: estradiol, progesterone, testosterone, follicle-producing hormone, luteinizing hormone and prolactin. When endocrine abnormalities occur, the corresponding hormone levels will also change. Generally, when irregular menstruation, non-functional uterine bleeding, infertility, etc. occur, it is necessary to go to the hospital in time to check the hormone six. Clinically, it is more accurate to go to the hospital on the 2nd-3rd day after the onset of menstruation to check the sex hormone 6 test. For women who usually have irregular periods, there is no clear rule that it is best to check hormone 6 on the first day of menstruation, but you can follow the doctor’s instructions to check at any time according to your own situation. Hormone levels have a close relationship with mood, work and rest, etc. Do not have sex or take other drugs before the test, and keep enough sleep and a good mood, so that the results will be more accurate.
