[Case of Rh E and Kell antigen sensitization by blood transfusion]

The case of a woman patient has been described. The patient suffered from trombocytopenia and hemorrhagic diathesis and was treated, apart of other therapy, with fresh blood transfusion. As the compatibility tests with some blood samples have shown positive results, a detailed immunohaematic analysis of the patient's blood and blood samples ready for transfusion has been carried out. It has been concluded that the patient was immunized with E Rh and Kell antigen that resulted in a positive compatibility test.
