Blood uric acid 450μmol/L is higher than the normal uric acid value, which is abnormal and is elevated uric acid, and can be treated by restricting high-purine foods and uric acid-lowering drugs. The saturation concentration of uric acid is 420μmol/L at 37℃ in the body. When blood uric acid is higher than 420μmol/L it will form crystals deposited in the kidneys, synovial membrane of joints, etc. and cause tissue damage. Currently, it is considered that a fasting blood uric acid level >420µmol/L on two occasions not on the same day with a daily diet is sufficient for the diagnosis of hyperuricemia. Therefore, a blood uric acid of 450µmol/L is considered abnormal and is elevated uric acid. Generally, elevated uric acid can be treated by limiting the intake of high-purine foods such as pig liver, limiting alcohol consumption, and taking uric acid-lowering drugs such as allopurinol and benzbromarone when necessary. It is recommended that patients find high blood uric acid timely to regular hospitals, consult a doctor, according to the condition of the choice of appropriate treatment.
