Serum Uric Acid
What Is This Test?
The Serum Uric Acid test is a blood test that measures the amount of uric acid present in your bloodstream. Uric acid is a waste product formed when the body breaks down substances called purines, which are naturally found in the body and in foods such as red meat, seafood, and certain alcoholic beverages.
Normally, uric acid is filtered by the kidneys and excreted through urine. When the body produces too much uric acid or the kidneys cannot remove it effectively, uric acid levels can increase, leading to conditions such as gout, kidney stones, and chronic kidney disease.
Why this test is performed?
Doctors may recommend the Serum Uric Acid test to:
- Diagnose gout
- Evaluate joint pain and swelling
- Monitor gout treatment
- Assess the risk of kidney stones
- Evaluate kidney function
- Monitor patients receiving chemotherapy
- Investigate recurrent joint inflammation
- Assess metabolic disorders
- Monitor patients with high uric acid levels
- Evaluate unexplained arthritis symptoms

Fasting is usually not required, but some laboratories may recommend 4–8 hours of fasting for more consistent results.
Drink plenty of water before the test unless instructed otherwise.
Avoid alcohol for at least 24 hours before the test if possible.
Avoid excessive intake of high-purine foods (such as organ meats and certain seafood) before testing if advised by your doctor.
