On the second day of menstruation, women can usually have a blood test for hormone 6 on an empty stomach, which is mainly to understand the basal function of the ovaries. However, during menstruation, the progesterone level is at its lowest and there is no monitoring effect. Therefore, the Hormone 6 test, which is done on the second day of menstruation, mainly looks at the levels of several other hormones. For example, the levels of luteinizing hormone, follicle stimulating hormone, estrogen, testosterone and lactogen are normal. The normal levels of these hormones will help to rule out most endocrine disorders, such as polycystic ovary syndrome, high testosterone levels, and luteinizing hormone levels. In addition, if a woman wants to know how the luteal body is functioning, a blood test for progesterone level is usually taken about a week before her period to find out how the luteal body is functioning.
