Which test is ABO typing plus antibody screening that can be used to crossmatch in the future?

• A. T&C
• B. Mono Spot
• C. LFTs
• D. UA

Answer: (A)

The test described is designed to establish compatibility for future transfusions by confirming the patient's blood group, checking for antibodies that could cause reactions, and then validating compatibility with donor cells. ABO typing identifies whether the patient is A, B, AB, or O, while an antibody screen looks for unexpected antibodies that could react with donor red cells. When a crossmatch is performed, donor red cells are tested against the patient’s serum to ensure there won’t be a hemolytic reaction during transfusion. Having this crossmatch-ready setup allows you to proceed quickly if a transfusion becomes necessary later, which is why this choice fits “ABO typing plus antibody screening that can be used to crossmatch in the future.” The other options don’t address transfusion compatibility at all: LFTs and urinalysis assess organ function and urine characteristics, and Mono Spot screens for mononucleosis, not transfusion compatibility.
