How Is Premature Menopause/Pre Menopause Diagnosed?
First, your doctor will most likely perform a physical exam and draw blood to rule out other conditions, such as pregnancy and thyroid disease. He or she may also order a test to measure your estradiol levels. Low levels of estradiol, a form of estrogen, can indicate that your ovaries are starting to fail. When estradiol levels are below 36, it may signal that you are in menopause. However, the most important test used to diagnose premature menopause is a blood test that measures follicle stimulating hormone (FSH). FSH causes your ovaries to produce estrogen. When your ovaries slow down their production of estrogen, your levels of FSH increase. When your FSH levels rise above 30 or 40 mIU/mL, it usually indicates have POI – pre menopause.
