This blood test measures the amount of uric acid in your blood. Uric acid is a natural waste product your body makes when breaking down substances called purines, which are found in certain foods and drinks and your own cells. Normally, uric acid dissolves in your blood, passes through your kidneys, and leaves your body in urine.
A high level of uric acid in the blood may be associated with gout—a type of arthritis—and could increase the risk of kidney stones. However, not everyone with a high uric acid level will develop these conditions. Some medications can also raise uric acid levels.
Checking uric acid level may be useful for those with gout symptoms (sudden, severe joint pain, swelling, and redness—often in the big toe), a family history of gout, those with chronic kidney disease, or other health conditions.
Note: This test does not diagnose specific health conditions. It is recommended to consult with a healthcare provider if you have any questions about your result.
