Blood uric acid test to fasting, also need to test urine

Blood uric acid test generally requires fasting, do not need urine test.

Blood uric acid test is to check the content of uric acid in the blood by drawing blood. If the patient eats a lot of purine food before the test, such as animal liver, shellfish seafood, etc., it may cause false increase in blood uric acid level; if drinking a lot of water before the test, it will dilute the urine and easily make the blood uric acid level false decrease, so it generally needs fasting before the test. In addition, blood uric acid is tested by drawing blood, so urine test is generally not required.
