The six hormone tests for women include: i) luteinizing hormone; ii) ovulatory hormone; iii) estradiol; iv) progesterone; v) testosterone; and vi) prolactin. In order to have a blood test for the six endocrine hormones, it is necessary to have the blood test on an empty stomach on the second to fifth day of menstruation. Some women may have endocrine hormone disorders that prevent them from having a normal menstruation and cause a delay in menstruation, so they do not have to wait until their menstruation to have the blood test, but can have the blood test at any time, as long as they choose to have an empty stomach. The six endocrine hormone tests can determine whether there is premature ovarian failure, whether there are polycystic ovaries caused by high androgens, whether there is prolactinemia caused by prolactin, and whether estrogen and progesterone are low, as these hormone levels can reflect normal ovarian function.
