Uric Acid, Body Fluid
Use
Measurement of uric acid in body fluid is clinically useful when evaluating pathophysiologic conditions such as gout or crystal-induced arthropathies and related disorders; it helps assess urate crystal burden in synovial, pleural, peritoneal, or other body fluids for diagnostic and management purposes.
Special Instructions
Specimen must be centrifuged to remove cellular material, then 1 mL aliquoted into a plastic vial, frozen for transport, and the source of the fluid must be provided. Testing is performed daily (Monday through Sunday) by ARUP Laboratories.
