Uric Acid Test: Diagnosing and Monitoring Gout
A uric acid test measures the level of uric acid in the blood or urine. Uric acid is formed when the body breaks down purines, and high blood levels, called hyperuricemia, can lead to gout and kidney stones. Not everyone with high uric acid develops gout, and uric acid can be normal during an acute attack. The test is used to help diagnose gout and to monitor treatment that lowers uric acid, with results interpreted alongside symptoms and other tests.
