The normal value of blood uric acid is 150-416umol/L for men and 89-357umol/L for women. Blood uric acid is mainly related to glomerular filtration function and tubular reabsorption function, the normal value for men is 150～416umol/L, and for women is 89～357umol/L. Blood uric acid is more accurate when purine-rich food is strictly prohibited for 3 days, and exogenous uric acid interference is excluded. Elevated blood uric acid concentration may be due to glomerular filtration injury, abnormal increase in uric acid production in the body, and decreased uric acid may be acute hepatic necrosis, hepatomegaly, and so on.
