Quizplus · Accepted Answer

A positive direct antiglobulin test (DAT), also known as a direct Coombs test, indicates the presence of antibodies or complement proteins attached to red blood cells in the body.

Other causes of a positive DAT include transfusion reactions, hemolytic disease of the newborn, and drug-induced hemolytic anemia. Therefore, the most likely choice is A, autoimmune hemolytic anemia.
