Estrogen, Total, Serum

Estrogens are hormones that play an important role in the development of female physical characteristics and reproductive functions. Estrogens are also produced in men but in much lesser amounts as compared to women. In general, estrogens are of three types namely Estrone (E1), Estradiol (E2), and Estriol (E3). The Estrogen, total, serum blood test is used to measure the levels of estrogens in the blood. The test is used to find out the cause of infertility, to detect the symptoms of menopause, or to monitor the treatment for the same. It is also used to screen and diagnose menstrual problems in women, the reasons for late puberty in boys, and sometimes it can also be used to screen and monitor a high-risk pregnancy.
