The uric acid urine test measures the level of uric acid in urine. Uric acid level can also be checked using a blood test. 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.

SPECIMEN: 10 mL (5 mL min.) aliquot of 24 hour urine. Do not use preservatives. Ship refrigerated or frozen. Record 24 hour volume on test request form and urine container.
STABILITY: Room: 2 hrs; Refrigerated: 1 week; Frozen: 4 weeks
REPORT: Daily
USAGE: This assay is useful for the assessment and management of patients with kidney stones, particularly uric acid stones. Urinary uric acid excretion is elevated in a significant proportion of patients with uric acid stones, due to uric acid overproduction as in Leukemia and Polycythemia and after intake of food rich in nucleoproteins.
