Uric acid is the end product of purine metabolism. Disorders of purine metabolism, abnormal energy metabolism, and renal excretion of uric acid can cause plasma uric acid concentrations to increase (hyperuricemia) or decrease (hypouricemia). Currently, uric acid measurement is considered to be the best biochemical marker for diagnosing gout caused by disturbance of purine metabolism. The main feature of gout is hyperuricemia, which causes acute gouty arthritis, tophi deposition, tophi-induced chronic arthritis and joint deformities, uric acid nephrolithiasis and other kidney diseases, which are very harmful to health. Uric acid measurement also helps in the early diagnosis of kidney disease.
