On Demand Medical Testing

An estrogen test measures the level of the most important estrogen hormones (estradiol, estriol, and estrone) in a blood or urine sample.

• Estradiol is the most commonly measured type of estrogen for nonpregnant women. The amount of estradiol in a woman's blood varies throughout her menstrual cycle. After menopause, estradiol production drops to a very low but constant level.
• Estriol levels usually are only measured during pregnancy. Estriol is produced in large amounts by the placenta, the tissue that links the fetus to the mother. It can be detected as early as the 9th week of pregnancy, and its levels increase until delivery. Estriol can also be measured in urine.

Estrone may be measured in women who have gone through menopause to determine their estrogen levels. It also may be measured in men or women who might have cancer of the ovaries, testicles, or adrenal glands.

Your adrenal glands are two small pieces of tissue that sit atop each kidney. They  produce and release certain regulatory hormones and chemical messengers - one of which is Dehydroepiandrosterone Sulfate or DHEA-S for short. It’s a natural steroid hormone produced from cholesterol and it purpose is to serve as a precursor to male and female sex hormones. This hormone is also associated with immune and stress response.
