Uric acid 447μmol / L is considered high uric acid. Normal adult male blood uric acid value is 150~416μmol/L, female blood uric acid normal value is 89~357μmol/L, clinically non-same day 2 times fasting blood uric acid more than 420μmol/L defined as hyperuricemia, so the blood uric acid 447μmol/L is considered to be high uric acid. Hyperuricemia is caused by factors such as impaired purine metabolism and increased uric acid production. For patients with hyperuricemia, patients should eat less seafood, animal offal and other high purine foods, drink more water, and exercise properly every day. If the review of uric acid continues to rise, such as healthy people continue to be higher than 540 μmol / L, it is recommended to follow the doctor’s advice to promote uric acid excretion of drugs, such as benzbromarone, probenecid, as well as febuxostat, allopurinol, and other inhibitors of uric acid production of drugs for uric acid reduction therapy. Patients with elevated uric acid should seek medical attention in a timely manner and take appropriate measures for treatment under the guidance of a doctor.
