Clinical Significance
Urine uric acid may supplement serum uric acid testing when trying to identify conditions in which there is alteration of uric acid production or excretion e.g., gout, leukemia, renal disease. The amount of uric acid excreted may be useful in treating asymptomatic hyperuricemia. Measurement of urine uric acid is important in the investigation of urolithiasis.
