Estrogens, Total

The estrogens test measures the total amounts of the most important estrogens including estradiol, estriol, and estrone in the blood. Estrogens are the hormones responsible for female sexual development and function. In women, estrogens are produced primarily in the ovaries. Small amounts of estrogens are produced by the adrenal glands and testicles in men.

The estrogens blood test is used to monitor fertility therapies, detect fetal birth defects, identify tumors in the ovaries of girls before menstruation and in women after menopause, and help detect tumors in the testicles of men.
