New Developments in the Understanding and Treatment of Autoimmune Hemolytic Anemia: Traditional and Novel Tests

Careful consideration of the clinical history with traditional testing such as an antibody screen and direct antiglobulin test (DAT) allow for the categorization of most forms of autoimmune hemolytic anemia. Based on the initial findings, specialized testing can further categorize disease entities and increase the sensitivity of testing. In this section, we explain the diagnostic findings of both traditional and novel testing and how their appropriate interpretations help distinguish the forms of autoimmune hemolytic anemia (AIHA).
