Multiple Choice

Which statement correctly describes the antigens that are negative on a unit designated D-C-E-c+e+?

In this notation, plus or minus beside each Rh antigen shows whether that antigen is present on the red cells. A designation like D-C-E-c+e+ means D, C, and E are absent (negative), while c and e are present (positive). So the antigens that are negative on this unit are D, C, and E. The statement that lists D negative and C negative lines up with those negatives. E is also negative, though that particular option doesn’t mention it. This is why that choice is the best match among the options: it correctly identifies the known negative antigens (D and C) on the unit, with E also negative by the designation. Understanding this helps anticipate potential antibody formation and ensures compatible matching for transfusion.
