title: Allergic transfusion reaction caused by the shrimp allergen of donor blood: a case report.
abstract: OBJECTIVE
  The purpose of this report is to analyze the cause of allergic transfusion reaction.
  
  
  METHODS
  The methods of immunoblot and immunonephelometry were applied to detect the levels of the immunoglobulins of IgA (Immunoglobulin A) and IgE (Immunoglobulin E) and the level of sIgE (specific Immunoglobulin E) to shrimp allergen both in the patient's pre and post transfusion blood samples, respectively.
  
  
  RESULTS
  After transfusion, The level of sIgE to shrimp showed "increase" corresponding to the concentration of 0.70-3.5 IU/ml.
  
  
  CONCLUSIONS
  The allergic transfusion reaction was very likely caused by passive transfer of shrimp antigen to the patient allergic to shrimp.
