Tests and diagnosis

By Mayo Clinic Staff

Tests to help diagnose gout may include:

  • Joint fluid test. Your doctor may use a needle to draw fluid from your affected joint. When examined under the microscope, your joint fluid may reveal urate crystals.
  • Blood test. Your doctor may recommend a blood test to measure the uric acid level in your blood. Blood test results can be misleading, though. Some people have high uric acid levels, but never experience gout. And some people have signs and symptoms of gout, but don't have unusual levels of uric acid in their blood.
