Diagnostic Use

Uric acid is a breakdown product produced from the metabolism of the purine bases (adenine and guanine). Elevated uric acid levels in the blood can serve as a valuable indicator for various medical conditions, such as gout and the metabolic syndrome. Monitoring plasma uric acid levels aids in the diagnosis, risk assessment, and management of these conditions.
