Test Name
Uric Acid
Specimen Type & Acceptability
Serum
5 days refrigerated.
General Use
Increased uric acid levels are found in uremia, gout, destruction of an unusual amount of body tissue (such as the treatment of leukemia), diabetic acidosis, and the ingestion of certain toxic substances and drugs.
The serious consequences of abnormal uric acid metabolism depend in part upon the insolubility of uric acid. Uric acid can crystallize in the kidney and urinary tract resulting in gout. Decreased uric acid levels can be found in drug therapy.
