Which test is used to determine blood type and crossmatch preoperatively?

• A. Blood type & crossmatch
• B. CBC
• C. ECG
• D. Chest X-ray

Answer: (A)

Preparing for possible transfusion requires confirming the patient’s blood type and ensuring donor compatibility through crossmatching. The test that provides both the ABO/Rh blood type and a crossmatch with donor cells is the blood type and crossmatch. It identifies the patient’s blood group and screens for antibodies, then performs a crossmatch to confirm that a potential donor unit will be compatible, reducing the risk of transfusion reactions during and after surgery. A complete blood count is useful for assessing anemia, bleeding risk, and overall cell counts but does not determine blood type or donor compatibility. An ECG evaluates the heart’s electrical activity and helps identify rhythm or conduction problems. A chest X-ray assesses the lungs and heart size and can reveal thoracic pathology, but it does not address blood typing or crossmatching.
