Why This Biomarker Matters

Estrogen levels affect menstrual health, fertility, bone strength, and cardiovascular function. Abnormal levels may indicate hormonal imbalances or reproductive disorders requiring evaluation.

Overview

Estrogen is a primary female sex hormone produced mainly by the ovaries, though also made in smaller amounts by other tissues. A 24-hour urine estrogen test measures total estrogen excretion over a full day, reflecting overall hormone production. This test helps evaluate hormonal imbalances, menstrual irregularities, fertility issues, and certain hormone-related conditions. Abnormal levels may indicate ovarian dysfunction, polycystic ovary syndrome (PCOS), or other endocrine disorders.
