Fasting is required to test blood uric acid. Blood Uric Acid is a biochemical test that is important for the diagnosis of gout, assessment of the extent of the condition, and evaluation of the effectiveness of treatment. The level of blood uric acid in the body is affected by a variety of factors such as diet, exercise, and medication, so to get accurate blood uric acid results, you need to strictly follow the requirements of uric acid testing, such as fasting. In addition, patients are generally required to eat a light diet before the test, without eating high purine foods (such as shrimp, crab, etc.), while fasting for more than 8 hours before the test. In addition, try not to take drugs that lower uric acid levels before testing blood uric acid, so as not to affect the true test results. It is recommended that patients who need to test their blood uric acid should go to a regular hospital in time and follow the doctor’s instructions for the test.
