Serum or plasma concentration of uric acid (mass concentration)

Why Is This Test Done?

Your healthcare provider may order this test to diagnose or monitor conditions such as gout, kidney disease, or to check for high uric acid levels that could lead to kidney stones or other health problems. It may also be used during certain medical evaluations, such as before chemotherapy or to assess metabolic health.

What to Expect Before the Test

No special preparation is needed for this test. You may have a blood draw from a vein in your arm, or if testing urine, you’ll collect a sample in a container. If you’re on a low-purine diet or have certain medications, your provider may advise adjustments.

What the Results Mean

Results are compared to a general reference range, but exact values can vary by lab. High levels may suggest conditions like gout, kidney problems, or metabolic disorders, while very low levels might indicate rare genetic or metabolic issues. Your provider will discuss findings in the context of your overall health.

Common Conditions Linked to Uric Acid Levels

Elevated uric acid is often linked to gout, kidney dysfunction, or conditions like diabetes or hypertension. Low levels are less common but could relate to genetic disorders or certain medications. Your provider will interpret results based on your symptoms and medical history.
