Routine blood tests and coagulation function tests are common check-up programs for hepatitis patients upon admission. Anticoagulation in the blood test results refers to the anticoagulant coating inside the test tube, which is used to prevent blood from clotting. This anticoagulation does not refer to the type of your blood but the type of the test tube. This result does not have special significance for diagnosing the condition. Hematological tests may require anticoagulation or not, depending on the specific project. Currently, the test tubes used in hospital laboratories are generally pre-filled with anticoagulants and are vacuum tubes, making them convenient and non-contaminating to use.
