Hormone 6 is a major test to determine whether there is premature ovarian failure, polycystic ovary syndrome, hyperprolactinemia, or hyperandrogenemia, and the test is performed on the second day of menstruation, with blood drawn on an empty stomach. You should register for the gynecology and endocrinology department to check the hormone six, and choose to have the blood drawn around 9:00 a.m. It is necessary to combine clinical manifestations, gynecological outpatient examination, and gynecological ultrasound to jointly assess the nature of the disease. For women with excessive hyperprolactinemia, further cranial MRI is needed to determine if there is a pituitary tumor. For patients with polycystic ovary syndrome, gynecologic ultrasound is also needed to determine whether the ovaries have polycystic-like changes.
