Uric acid 366umol/L is not considered high. Uric acid is a product of purine metabolism, mainly produced by cell metabolic breakdown of nucleic acids and purines in food by the action of enzymes. Hyperuricemia is diagnosed when it is greater than 420umol/L. Human body temperature at 37 degrees Celsius, the saturation concentration of uric acid is 420umol / L, more than this value, urate formation of crystals deposited in various tissues, such as kidneys, joints, etc., causing uric acid nephropathy, gouty arthritis and so on. In order to reduce the production of uric acid, usually eat less food containing more purines, such as animal offal, beer, seafood, etc., and drink more water to promote the excretion of uric acid. Uric acid 366umol/L is a normal level and attention to lifestyle is sufficient. If accompanied by joint pain, it is recommended to go to the hospital, under the guidance of the doctor treatment.
