Clinical Definition of Uric Acid

Uric acid is a chemical created when the human body disintegrates substances called purines. Purines are found in food like liver, mackerel, dried beans and peas and drinks like beer and wine. Purines are also a part of normal body substances such as DNA. 

Uric acid gets dissolved in blood and is filtered from the body by the kidneys and excreted in the urine. Any remnants are removed through the stool. If uric acid is produced in excess or in lesser quantities, it accumulates in the body causing high levels of uric acid in the blood (hyperuricemia). The presence of excess uric acid causes gout, a state characterized by inflammation that impacts the joints when crystals derived from uric acid are formed in the joint (synovial fluid). Excess uric acid also leads to kidney disease.

Why Get Tested?

The uric acid blood test is carried out to determine the levels of uric acid in the blood and monitor these levels in people undergoing chemotherapy or radiation treatment. This test is used to diagnose gout and the cause of recurrent kidney stones.
