MPHO Type: 
Estimated frequency: 
Case Report. Acute hemolytic transfusion reactions following the administration of ABO-incompatible plasma in platelet concentrates have been reported but their potential severity is often not appreciated since it is not common.
Time to detection: 
During transfusion
Alerting signals, symptoms, evidence of occurrence: 
During transfusion of type O apheresis platelets into a type A recipient, patient experienced chills, back pain.

Imputability grade: 
3 Definite/Certain/Proven
