Estradiol is a steroid hormone in the human body that represents estrogen and comes from cholesterol. Estradiol is a critical part of sexual and reproductive function – acting as an anti-oxidant neuroprotective agent and known to be profoundly associated with bone growth. Estradiol is also suspected to play a large role in cancer of breast and uterine endometrial lining. 

If you are experiencing any of the signs and symptoms below, measuring your Estradiol levels may assist you and your physician in making accurate and conclusive diagnosis. This saliva Estradiol imbalance testing service can tell you if your Estradiol levels are within the expected optimal range depending on your age and sex. It can be very helpful to you and your physician in determining if the observed complications are in any way associated with Estradiol signaling or not.
