Substance concentration of uric acid in serum/plasma

Why This Test Matters

Uric acid is a waste product that your body produces when it breaks down purines, which are found in certain foods and are also created naturally. High levels can indicate conditions like gout, kidney problems, or other metabolic disorders. Your doctor may order this test to diagnose or monitor these conditions or to check for kidney function.

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 drawing blood. If you’re taking medications that affect uric acid levels, let your healthcare provider know. Avoid strenuous activity or eating certain foods (like high-purine foods) for a few days before testing if instructed.

How the Test Works

A small sample of your blood is drawn from a vein, typically in your arm. The sample is then sent to a lab where it is analyzed using a specialized method to measure uric acid concentration. This test provides a snapshot of your current uric acid levels in your bloodstream.

Possible Results and Next Steps

Results may be compared to a reference range provided by your healthcare provider. High levels might prompt further testing or treatment to manage conditions like gout or kidney issues. Low levels may require additional evaluation to rule out deficiencies or other underlying causes.
