Hormone 6 can be checked during the 2nd to 5th day of menstruation. Sex Hormone 6 is a test of hormone levels by drawing blood from a vein to understand endocrine function and diagnose diseases associated with endocrine disorders. It includes luteinizing hormone, follicle stimulating hormone, progesterone, estradiol, prolactin, and testosterone. There are different phases within a woman’s menstrual cycle, such as the follicular phase, the ovulation phase and the luteal phase, and the level of hormone secretion varies during different phases. The follicular phase can be identified on the 2nd to 5th day of menstruation, and a sex hormone 6 test can be performed at this time to determine the range of the follicular phase. Therefore, it is best to go for the test on the 2nd~5th day of menstruation. Stop using sex hormone medication before having your blood drawn to check your sex hormone levels. Sit still for more than 30 minutes before the blood draw to avoid fluctuation of hormone levels due to exercise.
