A small portion of women cease menstruating abruptly with no previous signs of irregularity. But the majority of women experience menstrual irregularity and therefore need confirmation that they are experiencing post menopause. With this test a woman can determine if she is experiencing peri-menopause or post menopause to enable her to seek guidance and appropriate advice from her physician. FSH levels normally vary between 10 and 20 miU/ml in woman. After transition into post menopause these increase to over 25mU/ml.
