A single uric acid 500 μmol / L or simple hyperuricemia without other manifestations, the condition is mild; if combined with gout, gout stone, gouty nephropathy, and combined with metabolic diseases, cardiovascular and cerebral vascular diseases, etc., the condition is more serious. The clinical significance of elevated blood uric acid level is not significant. It is necessary to test the blood uric acid level twice on non-same day, and hyperuricemia can be diagnosed if both levels are higher than 420 μmol/L. The condition of pure hyperuricemia without other manifestations is relatively mild. When hyperuricemia is combined with arthritis due to urate deposition, gout is considered to be present and the condition is more serious. If the gouty patient then develops gout stones and impaired renal function, it suggests that the gout has entered the chronic stage and gouty nephropathy stage, and the condition is further aggravated. If the above conditions are combined with metabolic diseases (such as diabetes mellitus, hyperlipidemia), cardiovascular and cerebrovascular diseases (such as coronary heart disease, cerebral infarction, atherosclerosis), the patient’s condition is even more serious.
