Which test measures serum uric acid levels to evaluate gout?

• A. Creatinine clearance
• B. Amylase test
• C. Uric acid test
• D. Lipase test

Answer: (C)

Measuring serum uric acid levels is the test used to evaluate gout because gout involves the deposition of urate crystals formed from high levels of uric acid in the blood. By assessing how much uric acid is circulating, this test helps identify hyperuricemia, which is commonly associated with gout and can be used to support diagnosis and to monitor response to urate-lowering therapy. Keep in mind that during an acute flare, uric acid levels can sometimes be normal, but the test still directly reflects uric acid status, which is the relevant marker for this condition.

Creatinine clearance examines kidney function and filtration, not uric acid or crystal formation. Amylase and lipase measure pancreatic enzymes and are used to evaluate pancreatic inflammation, not gout.
