Why This Test Is Done
Doctors may order a 24-hour urinary estrogen test to evaluate hormonal health, especially in conditions like: - Hormone-related cancers (e.g., breast, ovarian) - Menopause or perimenopause symptoms - Reproductive health concerns (e.g., irregular periods, fertility issues) - Monitoring hormone therapy effects - Research or specialized clinical studies.
How the Test Works
You’ll collect all urine produced in a 24-hour period (typically from midnight to midnight) in a sterile container. The sample is then sent to a lab for analysis using a sensitive measurement method to detect estrogen levels in your urine.
Sample Collection Details
To prepare, empty your bladder at the start of the collection period. Store urine in a cool, dark place if not testing immediately. Avoid using sanitary products or tampons during collection. Report any missed urine to your provider.
What to Expect After the Test
Results are usually reported as a total amount of estrogen excreted (often in micrograms or milligrams) over 24 hours. Your doctor will interpret results based on your medical history and symptoms.
Clinical interpretation

Frequently asked questions
Estrogen levels in urine can indicate overall estrogen production and metabolism. Abnormal results may signal hormonal imbalances, cancers, or other reproductive health conditions. Always discuss results with your healthcare provider for personalized interpretation.
Results typically take 1–2 weeks to process and review, depending on lab turnaround times. Your doctor will contact you once they’re ready for discussion.
Avoid estrogen-containing medications (e.g., birth control, hormone therapy) or supplements (e.g., phytoestrogens) for at least 2 weeks before testing to ensure accurate results.
