Hyperuricemia is not the same as elevated uric acid. Hyperuricemia is defined as a fasting blood uric acid level higher than 420 μmol/L on two occasions not on the same day with a normal diet. High uric acid is defined as a uric acid level that exceeds the normal range, which may be transient or long-term, and long-term elevated uric acid may develop into hyperuricemia. Normal human blood uric acid level for women is 89~357μmol/L, men are 150~416μmol/L, more than the range suggests high uric acid, hyperuricemia refers to the normal dietary status, non-same day two fasting blood uric acid level is higher than 420μmol/L. The human body in eating a lot of seafood, animal offal and other high purine food, drinking a lot of alcohol or strenuous exercise may appear after a transient increase in uric acid, transient uric acid elevation can be in the patient for dietary adjustments, change lifestyle habits or rest after the return to normal. Decreased excretion of uric acid, diseases, drugs and organic acid production can also lead to uric acid elevation, persistent uric acid elevation may develop into hyperuricemia. It is recommended that patients go to the endocrinology department, rheumatology and immunology department of regular hospitals and other related departments for detailed consultation.
