Thrombotic thrombocytopenic purpura (TTP) is an uncommon thrombotic microangiopathic (TMA) disorder, frequently confused with other TMAs- typical and atypical hemolytic-uremic syndromes. TTP results from either inherited or acquired deficiency of ADAMTS13. Deficiency of ADAMTS13 results in failure to process ultra-high-molecular-weight multimers of von Willebrand factor, leading to widespread platelet thrombosis. This presentation will summarize TTP pathogenesis, laboratory features, distinguish TTP from the TMAs, suggest a laboratory pathway of diagnosis, and briefly describe current and future treatment options.
After attending this session, participants will be able to:
· Understand the pathogenesis of Thrombotic Thrombocytopenic Purpura (TTP).
· Distinguish TTP from other thrombotic microangiopathies (TMAs).
· Understand appropriate laboratory testing for diagnosing TMAs.
Who should attend? Practicing Pathologists, Residents, Doctoral Scientists, Bench Technologists & Technicians
