A Uric Acid test measures the level of uric acid in your blood, a waste product formed when the body breaks down purines found in certain foods and tissues. High uric acid levels can lead to gout, a type of arthritis causing sudden joint pain, swelling, and redness—often in the big toe. Elevated levels may also indicate kidney disease, dehydration, or metabolic issues. Low levels are less common but may be associated with liver disease or certain genetic conditions.

For the Uric Acid test, a small blood sample is collected from a vein. Fasting for 4–8 hours may be recommended, depending on your doctor’s advice. This test helps diagnose gout, monitor uric acid levels during treatment, and assess kidney function. It is often done along with other kidney or metabolic tests for a complete evaluation.
