Why Is This Test Done?

Your healthcare provider may order this test to check for gout, kidney disease, or other conditions that affect how your body processes uric acid. It can also be part of routine health screenings or monitoring for certain medications.

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. For urine tests, follow any instructions to collect a sample over 24 hours.

What Happens During the Test?

For blood tests, a small needle will draw a sample from a vein in your arm. For urine tests, you’ll collect a sample in a container over a specified period. The sample is then sent to a lab for analysis.

What Are Normal Results?

Results vary by lab and method, so your provider will interpret them based on your health and medical history. High or low levels may signal underlying issues that need further evaluation.
