Results
An estrogen test measures the level of the most important estrogen hormones (estradiol, estriol, and estrone) in a blood or urine sample.
Results are usually available within 24 hours.
Normal
For girls and women between puberty and menopause, estrogen levels vary throughout the menstrual cycle. Normal values may vary widely from lab to lab.

Many conditions can change estrogen levels. Your health professional will discuss any significant abnormal results with you in relation to your symptoms and medical history.
High values
High values may be caused by:
- Ovarian stimulation used to treat infertility (for example, before in vitro fertilization).
- Cancer, such as cancer of the ovaries, testicles, or adrenal glands.
- Serious liver disease (cirrhosis).
- A pregnancy with more than one fetus, such as twins or triplets.
- Early (precocious) puberty.
Low values
Low values may be caused by:
- Problems with ovarian function, which can be caused by a failure of an ovary to develop properly (Turner's syndrome) or because of a drop in pituitary gland activity.
- Anorexia nervosa.
- Menopause.
- A problem with the fetus or placenta during pregnancy.
