Vital transfusion in patients with multiple antibodies against common erythrocyte antigens

The transfusion of blood components could be needed in certain types of surgical procedures. Blood type components and the requested number of units will depend on the estimated loss of blood, type of surgery, surgical technique to be employed and risk factors for bleeding. Problems can appear when multiple antibodies against common erythrocyte antigens are detected in blood samples and this situation worsens if blood units are requested as quickly as possible. We report a case of a patient with a non frequent erythrocytic phenotype where multiple antibodies acting against high-frequency antigens were detected and who required urgent surgery.
