Which test is ABO blood typing and antibody screening that is crossmatched with the blood bank?

• A. LFTs
• B. T&S
• C. Urine preg
• D. Type and Cross (T&C)

Answer: (D)

In transfusion medicine, the key step before giving red blood cells is ensuring compatibility between the recipient’s antibodies and the donor cells. This happens by first determining the patient’s ABO and Rh type and screening for unexpected antibodies. If a unit will be transfused, a crossmatch is then performed between the patient’s serum (or plasma) and the donor red blood cells to confirm there won’t be a reaction. When both typing and crossmatching are included together, the process is known as Type and Cross. This is distinct from Type and Screen, which involves ABO/Rh typing plus antibody screening but does not include crossmatching with a donor unit. The other tests listed are unrelated to compatibility testing for transfusion.
