Estradiol (E2) Hormone
Fasting Required: No

Specimen: Blood

Results: 3-5 Business Days

Description: Estradiol, also known as E2, is the most active of the estrogens. For women, it is important to look at the relationship between estradiol and progesterone in evaluating menopausal symptoms such as hot flashes, mood disorders, and aging skin.

In men, high levels of estradiol are associated with abdominal fat, enlargement of the prostate and cardiovascular risk.

In both men and women, low levels of estradiol are associated with osteoporosis.

This test measures the bound, non-circulating, levels of estradiol.

Collection Instructions:
Note: For any patients for whom low estradiol levels are anticipated (e.g. males, pre-pubertal children and hypo-gonadal/post-menopausal females), the Quest Diagnostics Estradiol, Ultra sensitive, LC/MS/MS assay is recommended (test code 30289).

Methodology: Immunoassay (IA)

Note: Result turnaround times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
