What is this test?

This test measures urate (uric acid) and creatinine in urine. Urate is a breakdown product of purines, while creatinine is a waste product made by muscle metabolism.

Why might I need this test?

A clinician may order this test when evaluating conditions related to uric acid, such as gout or kidney stones, or when monitoring treatment for high urate levels. Creatinine in the same sample can help account for how concentrated or dilute the urine is.

How is the test performed?

A urine sample is collected and analyzed in the laboratory to measure the amounts of urate and creatinine. The results may be reported as measurements per volume of urine or as a ratio, depending on the laboratory report.

How do I prepare for the test?

Follow your clinician's or laboratory's urine-collection instructions exactly. The collection method and timing can affect the result, so tell the laboratory if a timed collection, such as a 24-hour collection, was requested.

Reference range

NCBI: Uric Acid Male 3.5-7.2 mg/dL; Female 2.5-6.8 mg/dLN/A

Specimen: urine

No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.

Clinical interpretation

Frequently asked questions

Why are urate and creatinine measured together in urine?
Creatinine helps show how concentrated the urine is. This allows a clinician to interpret the urate result more accurately, particularly when the urine collection is not complete or the patient is not well hydrated.
Does this test diagnose gout?
No, a urine urate measurement alone does not diagnose gout. Diagnosis usually depends on the clinical history, examination, blood tests, and sometimes analysis of fluid from a swollen joint.
Can medications or diet affect the results?
Yes. Urate levels may be affected by foods high in purines, alcohol, hydration, kidney function, and medicines such as allopurinol or febuxostat. Tell your clinician about relevant medications and supplements.
