What This Test Measures
Uric acid is a purine breakdown product. Excess leads to urate crystal deposition in joints (gout) and kidneys (urolithiasis).
Hyperuricemia is linked to obesity, metabolic syndrome, hypertension, and cardiovascular risk.
Levels depend on diet, renal excretion, and genetic factors.
