Transfusion Science Webinar​: Could it be drugs? How to differentiate AIHA from DIIHA

Abstract:
Learn to differentiate warm, cold, and drug-induced autoimmune hemolytic anemia through case-based serologic evaluation and practical antibody identification strategies.

This intermediate-to-advanced webinar explores how serologic patterns in warm and cold autoimmune hemolytic anemia (AIHA) can mask drug-induced immune hemolytic anemia (DIIHA). Through case-based analysis, participants will learn to identify key differences between these conditions using antibody identification and DAT results. The session emphasizes the importance of medication and transfusion history and outlines testing methods to confirm drug-dependent antibodies, equipping attendees with tools to improve diagnostic accuracy in complex hemolytic cases.
