when to get estrogen tested
An estrogen test measures the level of the most important estrogen hormones (estradiol, estriol, and estrone) in a blood or urine sample. 1  Estradiol is the most commonly measured type of estrogen for nonpregnant women.  Estriol levels usually are only measured during pregnancy.
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 be used to help determine the timing of a woman's ovulation and may be ordered to monitor the health status of the developing baby and placenta during pregnancy.
