Transfusion-Related Acute Lung Injury (TRALI)

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

Support TRALI investigation from the laboratory perspective, recognizing the notification trigger, quarantining the implicated unit, coordinating the donor follow-up interface, and documenting findings that distinguish TRALI investigation from clinical diagnosis alone.

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

  • Describe the laboratory's notification and unit-quarantine response when TRALI is suspected, and explain why the implicated unit and any co-components from the same donor require tracking
  • Explain the donor-antibody mechanism proposed for TRALI and why it drives a donor follow-up/notification interface rather than a patient-specimen test
  • Distinguish the laboratory's TRALI-support role (notification, quarantine, donor interface, documentation) from the clinical diagnosis of TRALI, which is made by the treating team using respiratory and imaging criteria
