Uric Acid — mg/dL to µmol/L

In short To convert uric acid from mg/dL to µmol/L, multiply by 59.4845 — so one mg/dL is 59.4845 µmol/L, and one µmol/L is 0.0168111 mg/dL. 6.0 mg/dL is 357 µmol/L; 6.8 mg/dL is 404 µmol/L; 7.0 mg/dL is 416 µmol/L. The factor comes from the molar mass, because uric acid has a molar mass of 168.11 g/mol; that is why it differs for every analyte and why a single "lab unit converter" factor does not exist. Uric acid is followed over time far more than most results — anyone managing gout is comparing this month's number with last year's — and the two unit systems make that comparison impossible without converting. 6.8 mg/dL and 404 µmol/L are the same figure, and it is the number most often quoted as the saturation point of urate in serum. This converts units. It does not interpret results, does not compare your value against a reference interval, and is not a substitute for the clinician who ordered the test — reference intervals differ between laboratories, methods and populations.
