For the year 1975, we examined 12,848 blood specimens using the type and screen as well as the crossmatch and detected 283 antibodies in 247 patients. Our screening reagent red blood cells were able to detect 96.11 per cent of these antibodies. If the antigen frequencies corresponding to those antibodies not detectable by our screening reagent red blood cells are taken into consideration. i.e., the incompatibility frequencies, the type and screen can be shown to be 99.99 per cent effective in preventing the transfusion of incompatible blood. Therefore, we believe that the type and screen may be safey substituted for the routine two‐unit crossmatch in those operative procedures usually not requiring transfusions. Adoption of this approach would reduce patient charges, provide for more efficient distribution of our limited blood supplies, and allow for more effective utilization of blood‐bank technologist time.
