Upper limit for Normal Uric Acid should be 4 mg/dL (240 mmol/L)
Most reference ranges that define normal uric acid include blood test results from people with excess uric acid but no gout symptoms. This is wrong because gout symptoms often develop later. Also, there are increased risks of heart disease, kidney disease, and other metabolic disorders. So labs should exclude all uric acid test results over 6.8 mg/dL.
When that is done, the normal range is 3 to 4 mg/dL for men and 2 to 3 mg/dL for women.
