Synonyms:

Urate

Clinical Use:

Uric acid measurements are useful in the diagnosis and treatment of gout, renal failure, and a variety of other disorders including leukemia, psoriasis, starvation, and other wasting conditions. Patients receiving cytotoxic drugs may be monitored with uric acid measurements. Only a minority of individuals with hyperuricemia develop gout. An increased uric acid level does not necessarily translate to a diagnosis of gout.3 The therapeutic goal for uric acid-lowering therapy is to promote crystal dissolution and prevent crystal formation. This is achieved by maintaining a uric acid level <6 mg/dL.
