Estradiol

An estrogen test measures or monitors your estrogen levels to detect an abnormal level or hormone imbalance.

Estrogen tests are used to detect a deficiency or excess in a woman and to help diagnose a variety of conditions associated with this imbalance. They may also help determine the timing of a woman’s ovulation and monitor the health status of the developing baby and placenta during pregnancy. In a man, estrogen testing may be performed to detect a hormone excess and its cause.
