Whether eating meat has any effect on the blood test needs to be judged according to the items to be tested. 1. Blood test requires fasting items such as biochemistry complete set, liver function, lipid complete set, fasting blood glucose, etc., which must be fasting before doing these items, otherwise it will affect the accuracy of the test, so eating meat will have an effect on the test of these items, such as lipids will be higher than the normal value. 2. Blood test can not be fasting blood sampling projects are routine blood, coagulation function, blood transfusion before eight, blood type, etc., if you do these tests before eating meat on the blood test results have almost no effect. Therefore, whether eating meat has any effect is related to the items that require blood tests. It is recommended that you do not eat high-fat food, overeat, drink, etc. the night before the blood test, and try to rest as early as possible, so that the results of the test the next day may be more accurate.
