TACO (Transfusion-Associated Circulatory Overload)

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

Recognize the laboratory-relevant documentation clues that help distinguish TACO from TRALI, apply the correct hemovigilance reporting classification, and understand why volume and rate decisions belong to the clinical team, not the laboratory.

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

  • Describe the timing pattern and clinical picture typically reported as TACO, and identify which parts of that picture the laboratory documents versus which parts the clinical team assesses
  • Compare the laboratory-relevant documentation clues that help distinguish TACO from TRALI when a reaction report describes respiratory distress during or shortly after transfusion
  • Apply the correct hemovigilance reporting classification for a suspected TACO episode and describe the laboratory's product-disposition and documentation responsibilities
