If you're struggling with severe, sudden joint pain, this test is a crucial step to finding the answer. The Uric Acid Serum test measures the amount of uric acid in your blood. When levels are too high, sharp crystals can form in your joints, causing the intense pain of gout. High levels are also linked to kidney stones. This test is essential for diagnosing gout and for monitoring the effectiveness of your treatment plan. A simple blood draw can help you and your doctor create a plan to manage your symptoms.
