Question

A patient's antibody screen and autocontrol react at 37 C and the antiglobulin phase with nearly all reagent cells. The DAT is positive with anti-IgG. What is the most important next objective before selecting red cells?

Accepted Answer

보기 2: Use adsorption methods to investigate whether clinically significant alloantibodies are masked by the warm autoantibody

A broadly reactive warm autoantibody can mask clinically significant alloantibodies. Adsorption and review of transfusion history help separate autoantibody reactivity from underlying alloantibodies before compatible antigen-negative units are selected.
