Question

Quizplus · Accepted Answer

The finding of a positive Direct Antiglobulin Test (DAT) and slight hemolysis suggests a possible immune-mediated hemolytic reaction. An elution procedure is the best choice following a positive DAT to allow the identification of the specific antibody involved in the reaction. The other tests listed may be useful in assessing the extent and severity of hemolysis, but they are not specific to identifying the antibody responsible for the reaction.
