Presented by

Dr. Ahmad Alharbi
Transfusion Medicine Physician Trainee
McMaster University, Hamilton

Learning objectives

1. Review the pathogenesis and definition of IVIG related hemolysis.
2. Identify the incidence and risk factors for IVIG related hemolysis.
3. Recognize the IVIG products with low isoagglutinin titers.
4. Criticize the product associated risk factors reported in the literatures.
