A blood uric acid concentration of 637 μmol/L in a male or female patient is beyond the upper limit of the normal reference range and is abnormal. Under normal circumstances, the reference range of blood uric acid concentration in adult men is 150~416 μmol/L, while the reference range of blood uric acid concentration in adult women is 89~357 μmol/L, beyond which is abnormal, and 637 μmol/L is far beyond the upper limit of the normal reference range, suggesting that the patient may have hyperuricemia. If the patient is diagnosed with hyperuricemia and the blood uric acid value is higher than 540 μmol/L in two consecutive tests not on the same day, then regardless of whether or not gout, gouty nephropathy and other complications occur, or whether or not accompanied by cardiovascular disease and cardiovascular risk factors, the patient should start medication to lower uric acid such as febuxostat, etc., and the uric acid should be controlled to less than 420 μmol/L. In addition, the patient should pay attention to his own dietary habits, and the patient should be aware of his own habits. In addition, patients should pay attention to their own dietary habits, avoiding a large intake of high-purine foods such as animal offal and seafood, and avoiding heavy alcohol consumption. It is recommended that patients with uric acid 637μmol/L should go to regular hospitals in a timely manner for treatment under the guidance of doctors.
