Estradiol (E2) Blood Test
Estradiol is one of the three many types of estrogen. The other two are estrone and estriol. Estradiol is produced in the body by testosterone. Estradiol (E2) is the most potent form of estrogen and is produced by the ovaries. Estradiol is measured to assess for menstrual problems, fertility issues, menopause status or as a tumor marker in patients with cancer. When estradiol decreases after menopause, it can lead to an increase in bone loss and can cause osteoporosis.
Methodology: Immunoassay (IA)
Water: Drink plenty of water to stay well hydrated.
Medications: Take all medications as prescribed.
Dietary supplements: If you take a dietary supplement containing Vitamin D, discontinue the dietary supplement 48 hours (two days) prior to the blood test. This will give a more realistic picture of a person’s Vitamin D status.

While women and men both produce estradiol, women make a lot more of it. Estradiol is an important in female reproductive system. It increases during puberty and is important for fertility and reproduction. But estradiol has many other roles. It is a potent antiinflammatory chemical.

- Decreased quality of life
- Heart disease
- Hot flashes
- Low libido
- Ovarian failure
- Poor blood sugar control and increased diabetes risk
- Vaginal dryness
