The reason to check kidney function for high uric acid is because decreased glomerular filtration, suppressed tubular secretion and increased tubular reabsorption may cause high uric acid. 1. Decreased glomerular filtration: can also cause increased uric acid levels. Decreased glomerular filtration is often associated with renal insufficiency, renal failure and hyperuricemia. 2. Inhibition of renal tubular secretion: drug factors, toxic factors, endogenous metabolites may inhibit uric acid excretion or reabsorption increase, and the more important inhibitory factors are lactic acid and ketoacids. 3. Renal tubular reabsorption increase: hyperuricemia does not exclude the possibility that the proximal tubular reabsorption enhancement induced. Patients with high uric acid are advised to go to regular hospitals for further examination and treatment under the guidance of specialists according to the results.
