NO Not Accurate. Hormone testing if abnormal is indicative of perimenopause, but normal levels may not be accurate. I've tested people, who are close to menopause and had results consistent with a 20 year old one month followed by those of 55 year old the next month. Hormone testing is very inaccurate. Symptoms are the most important factor with shortened and irregular cycles (<26 days).
Menopause. Pituitary levels of FSH LH can be checked as well.
FSH and LH. Are more accurate especially FSH in determining menopause.
