A uric acid test is generally a blood uric acid test and should usually be done in the early morning on an empty stomach when venous blood is drawn. The test for uric acid is usually scheduled in the early morning on an empty stomach and requires more than 8 hours of fasting. Uric acid is a metabolite of purines, and a high-purine diet can increase blood uric acid. It should be noted that in the days before the test of uric acid try to avoid drinking alcohol and high purine diet, in order to reduce the impact on the uric acid test. Stop taking drugs that affect uric acid excretion a week before the blood draw, and avoid strenuous exercise before the blood draw, because strenuous exercise can make blood uric acid increase. If you are suffering from hyperuricemia, you need to visit the clinic regularly, review and monitor the uric acid, control the diet according to the doctor’s advice, and standardize the treatment reasonably. Before the uric acid test, it is recommended to go to the hospital to consult the doctor about the relevant precautions, if the value is abnormal after the test, you need to follow the doctor’s advice in time to avoid delaying the condition.
