Blood uric acid 514.3 μmol/L is usually serious. Hyperuricemia is diagnosed when two blood uric acid values >420 μmol/L on non-same day are diagnosed under normal circumstances, when the normal blood uric acid values are 150 to 416 μmol/L for men and 89 to 357 μmol/L for women. A blood uric acid of 514.3 μmol/L is considered elevated uric acid. As the disease progresses, patients with high uric acid may develop acute gouty arthritis, gouty stones, kidney lesions, and other conditions. Therefore, blood uric acid 514.3 μmol/L is usually a more serious condition. Patients with high uric acid should pay attention to the diet to reduce the intake of high purine food, eat more vegetables, fruits and drink more water, which is beneficial to the discharge of blood uric acid. Patients with elevated blood uric acid are advised to go to the hospital in time and follow the doctor’s instructions for treatment to avoid delays.
