Introduction
The results of the four pre-transfusion tests can be available within 24 hours. During blood transfusion, it is necessary to monitor the patient for any adverse reactions; if no adverse reactions occur, the transfusion can proceed normally. In addition, blood transfusion usually refers to the process of administering blood from a healthy donor intravenously into a patient's body, typically used for patients with severe blood loss due to trauma or surgery.
Under normal circumstances, results for the four pre-transfusion tests can be obtained within 24 hours.
The four standard pre-transfusion tests typically include hepatitis C antibody, hepatitis B surface antigen, HIV antibody, and syphilis antibody testing. The time required to receive test results varies depending on the hospital and location—some facilities may provide results within half a day, while others may take up to 24 hours. These four pre-transfusion tests are mandatory before surgery to prevent transmission of blood-borne diseases. Conducting these tests allows for a thorough assessment of the patient's condition prior to transfusion, helps doctors evaluate overall health, minimizes the risk of adverse reactions after transfusion, and ensures the safety of blood use in clinical settings. During the transfusion process, patients should be closely monitored for any adverse reactions; if none occur, the transfusion can proceed normally.
In addition, blood transfusion generally refers to the intravenous infusion of healthy donor blood into a patient’s body and is commonly used for patients who have experienced severe blood loss due to trauma or surgery.
