Uric acid test

Uric acid test

Overview

Uric acid urine test is performed to check for the amount of uric acid in urine. Urine is collected over a 24 hour period and is sent to the laboratory for testing. The most common reason for measuring uric acid levels is in the diagnosis or treatment of gout, because gout results from crystallization of uric acid crystals in joints. Some kidney stones are also composed of uric acid.
