The normal range for blood uric acid varies slightly between the reference values for men and women, and is slightly lower for women. The normal range of blood uric acid is generally 150~416 μmol/L for men and 89~357 μmol/L for women. Blood uric acid values higher than the reference range suggest that blood uric acid is elevated and may develop into hyperuricemia. If increased uric acid is combined with redness, swelling and heat pain in a single joint, consider the presence of gout. The causes of increased uric acid include excessive purine intake and excretion disorders, mostly due to unhealthy lifestyle habits such as staying up late, drinking alcohol, and consuming seafood, broth and other high-purine foods. In general, patients with hyperuricemia and gout need to control uric acid within the target range, but the presence of gout stones, urinary tract stones, etc., need to further control uric acid below 300 μmol/L. Uric acid control to the standard is the most important factor in controlling gout attacks. When high uric acid occurs, it is recommended to seek medical attention and receive uric acid-lowering treatment under the guidance of a doctor.
