  • Program Description

    Immune hemolytic anemia (IHA) is rarely drug-induced, therefore when it is caused by a drug-dependent antibody, laboratories and clinicians can struggle with identifying the issue. This boot camp will further the participant’s understanding of drug-induced immune hemolytic anemia (DIIHA), and how to identify a patient possibly experiencing this type of hemolytic anemia. DIIHA can mimic warm and cold autoantibodies so a discussion of the serologic findings and clinical information needed to differentiate them will be included. This program will also review different drugs known cause DIIHA and the importance of reviewing timing and dosage to further educate blood bankers/medical laboratory scientists and clinicians on what to look for in a patient medication history.

    Learning Objectives

    After participating in this educational activity, participants should be able to:

    • Describe the different categories of drug-induced immune hemolytic anemia (DIIHA).
    • List the most common drugs causing DIIHA.
    • Describe the serologic findings of DIIHA in the laboratory.
    • Distinguish drug-dependent antibodies from warm or cold autoantibodies.
    • Describe the current testing methodologies available for identifying drug-dependent antibodies causing DIIHA.
