What is this test?

This test measures follicle-stimulating hormone (FSH) and creatinine in urine. FSH helps regulate the menstrual cycle and sperm production, while creatinine can help determine how concentrated the urine is and whether a collection may be incomplete.

Why might I need this test?

Urine FSH may be evaluated as part of an assessment of reproductive function or fertility. Urine creatinine is often measured alongside it to help interpret the hormone result and evaluate the adequacy of the urine collection.

How is the test performed?

You provide a urine sample according to your clinician's instructions. The laboratory analyzes the sample for FSH and creatinine, and the results are reported together for interpretation.

How do I prepare for the test?

Follow the collection instructions provided by your clinic, including whether a timed or first-morning collection is required. Record the collection time and any missed samples, and tell your clinician about medications or supplements that may affect hormone measurements.

Reference range

Follicular: 3.5-12.5 mIU/mLN/A

Frequently asked questions

Is this the same as a routine urine creatinine test?
No. This test reports both urine FSH and urine creatinine, and the creatinine result is used to help interpret the FSH measurement and the collection.
Does an abnormal urine FSH result diagnose a fertility problem?
Not by itself. Results are interpreted with other hormones, medical history, cycle information, and sometimes blood testing.
Why do I need to report the urine collection time?
FSH levels can vary over the course of the day and across the menstrual cycle. The collection time helps the laboratory and clinician interpret the result correctly.
