Double failure of the Type and Screen.
"Type and Screen" programs have proved effective in reducing time and cost in the crossmatching laboratories, while still assuring safety when transfusion is necessary. However, there remains the possibility that the program will miss a patient with an antibody to a low-incidence donor antigen and that such a patient will receive blood from such a donor. The authors report on the actuality of that possibility happening twice within two months in one hospital.
