Blood uric acid 618 μmol / L for blood uric acid elevation, generally more serious, long-term persistent high uric acid state can cause acute gouty arthritis, uric acid urolithiasis, gout stone formation and chronic uric acid nephropathy and other diseases occur. Uric acid is the end product of purine metabolism, mainly by the cellular metabolic decomposition of nucleic acids and other purine compounds and purines in food by the enzyme decomposition and production. The saturation concentration of uric acid in the body at 37℃ is about 420µmol/L. Above this concentration, urate forms crystals that are deposited in a variety of tissues, including the kidneys and synovial membranes of joints, causing tissue damage. Blood uric acid >420µmol/L on two occasions not on the same day is currently defined as hyperuricemia. When the high uric acid state persists for a long period of time, some patients can gradually develop into gout and show clinical symptoms and positive signs such as acute gouty arthritis, uric acid urolithiasis, gouty stone formation, etc. In severe cases, it can also lead to the occurrence of chronic uric acid nephropathy and severely damage the kidney function. Therefore, blood uric acid 618μmol / L is more serious, need to pay attention. If the blood uric acid level is found to be elevated, it is recommended that the patient go to the hospital in time, and standardized treatment under the guidance of the doctor.
