Laboratory Investigation of Transfusion Reactions

This Medical Laboratory Science lesson in Blood Bank supports laboratory science learning and laboratory interpretation for medical laboratory students and professionals.

Execute the core transfusion-reaction laboratory algorithm from stop notification through extended workup triggers, clerical check, visual plasma inspection, DAT, repeat ABO/Rh, and the decision points that escalate a routine workup into hemolysis, septic, or TRALI/TACO-focused investigation.

Each objective below describes a transfusion-service laboratory competency, investigating and interpreting adverse transfusion reactions, not delivering bedside treatment.

  • Execute the immediate stop-notification and specimen/unit-retention sequence that begins every suspected transfusion reaction workup
  • Perform the core investigation algorithm, clerical check, visual plasma inspection, DAT, and repeat ABO/Rh typing, and state what each step is designed to detect
  • Identify the findings that trigger an extended workup (antibody identification, culture, TRALI/TACO-focused documentation review) and distinguish each triggered pathway from routine baseline testing
