Uric acid is the product of the body breaking down foods and the body's cells. This is a natural process, and every human produces uric acid. Uric acid is dissolved into blood, which is filtered in the kidneys. The uric acid is filtered out of the blood along with other toxins or waste material, and eliminated from the body through urine.
If a body produces too much uric acid or can not filter uric acid from the blood stream fast enough, a person may develop gout, kidney stones or kidney disease. The condition in which a person has excessive levels of uric acid is called hyperuricemia.
Hyperuricemia can be caused by cancer, gout, a diet high in purine or the body's inability to process purine. If a person is suspected of having hyperuricemia, a doctor may order a 24-hour urine test to check uric acid levels in urine. This test is painless, but involves collecting all urine eliminated from the patient over a 24-hour period. A doctor can also check uric acid levels in the blood with a simple blood test.Learn more about Blood
