title: Misleading hepatitis B testing in the setting of intravenous immunoglobulin.
abstract: Intravenous immunoglobulin (IVIG) is commonly used for a wide range of diagnoses, by multiple pediatric subspecialists. We report two cases of hepatitis B screening results post IVIG infusion, where positive anti-Hepatitis B core antigen serology tests indicated possible occult hepatitis infection, leading to a delay in care. However, serial antibody testing showed results consistent with the passive transfer of antibodies.
