Estrone (E1) — the estrogen that takes over after menopause. Made mostly from adrenal androgens in fat tissue, it is the one to measure when estradiol alone doesn't explain symptoms, bleeding after menopause, or estrogen excess in men. Estrone is one of the body's three main estrogens, alongside estradiol (E2) and estriol (E3). Before menopause it is a minor player: the ovaries make estradiol, and estrone mostly serves as a precursor that is converted into it. After menopause the ovaries stop, and estrone becomes the dominant estrogen — produced not by the ovaries but by the conversion of androstenedione, an adrenal androgen, in fat tissue by the enzyme aromatase. That is why estrone runs higher in people with more body fat, and why a postmenopausal woman can have a near-zero estradiol and still carry a meaningful estrogen load. Clinicians order estrone in a few situations: postmenopausal bleeding, where the question is whether peripheral estrogen production is stimulating the uterine lining; menopausal hormone therapy, especially oral estrogens, which are converted to estrone in the liver and raise E1 far more than E2, so the ratio tells you something about how the hormone is being delivered; estrogen excess in men, including breast tissue growth, where aromatase activity rather than testicular estradiol is often the source; and broader hormone workups — irregular or absent periods, PCOS, fertility — where estrone rounds out the estradiol picture. An estrone-to-estradiol ratio above one is also one of the markers of the menopausal transition. Results are reported in pg/mL against age- and cycle-specific ranges from the performing lab; the two labs we route to use different methods (Quest runs estrone by LC-MS/MS, Labcorp by immunoassay), so if you are tracking the number over time, repeat it at the same lab. ## Biomarkers measured - Estrone ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $49.99 | $55.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $49.99 | $55.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | BioReference (NY & NJ) | $49.99 | $55.99 | New York and New Jersey orders route here automatically | Rhode Island is not served.

No fasting required. If you still have a menstrual cycle, note the cycle day — ranges differ across the cycle. If you take estrogen therapy, draw at the same point in your dosing schedule each time (for oral estrogen, ideally before the day's dose). Not for use during pregnancy. For trend tracking, repeat at the same lab: Quest and Labcorp use different methods and their numbers are not interchangeable. ## Common questions about the Estrone (E1) test ### How long does it take to get Estrone (E1) test results?
