Uric Acid, Serum LabCorp

Uric acid in the body is mostly filtered out by the kidneys and passes through the urine. A small amount passes out of the body through the stool. If ample amounts of uric acid are being produced or if the kidneys are unable to remove it from the blood as normal, the level of uric acid in the bloodstream will increase. Elevated levels of uric acid in the bloodstream may cause solid crystals to form within the joints. This causes a painful condition known as gout. If gout remains untreated, these uric acid crystals can build up in the joints and nearby tissues; forming hard, lumpy deposits called tophi. High levels of uric acid may also cause kidney stones or kidney failure.
