The term 'Type & Screen' refers to which of the following?

• A. ABO/Rh typing and screening for unexpected antibodies
• B. ABO typing only
• C. Rh typing only
• D. Antibody identification

Answer: (A)

Type & Screen means performing ABO and Rh typing on the patient and screening for antibodies that could cause a reaction during transfusion. The ABO/Rh typing identifies the patient’s blood group and D antigen status, while the antibody screen tests the patient’s serum for unexpected alloantibodies against red cell antigens. This combination lets clinicians anticipate compatibility before transfusion. If the screen is negative and the ABO/Rh type matches, units can be crossmatched as needed to confirm compatibility. Antibody identification is done only if the screen detects an antibody, to determine its specificity and select antigen-negative donor units. So this description best fits the concept.
