Serum or plasma concentration of uric acid

Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like joint pain, kidney problems, or if they suspect conditions such as gout, kidney stones, or certain types of arthritis. It may also be used to monitor treatments for conditions affecting uric acid levels.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to fast for 8–12 hours before the test if it involves a blood draw. Hydration can help dilute uric acid levels, so drinking plenty of water may be advised. Avoid consuming alcohol or high-purine foods (like organ meats, shellfish, or red meat) for 24 hours before testing.

What the Test Results Mean

Uric acid levels can vary based on diet, hydration, and overall health. High levels may indicate overproduction of uric acid or impaired kidney function, while low levels are less commonly significant. Your results will be compared to reference ranges provided by your lab.

Common Conditions Monitored

Elevated uric acid is often linked to gout, kidney disease, or metabolic syndrome. Your provider may also use this test to monitor conditions like psoriasis, certain cancers, or after treatments that affect purine metabolism.
