title: The CAP blood bank comprehensive survey program--1975.
abstract: The 1975 CAP Comprehensive Blood Bank Survey Program showed that the ABO and Rh typings were again at an excellent level of performance. What few errors still occurred were at least partially explained by a study that showed that many of these errors were directly traceable to clerical mistakes; many, in fact, were due to a complete failure to submit an answer. Antibody detection was very good when the antibody was strong, but lower levels of performance were attained when the antibody was weak. Low performance was also achieved with a cold-reacting anti-I, but here the difficulty was found to be more a lack of agreement on terminology of the antibody rather than a failure to demonstrate it. A study was performed to see whether the participants that were late in sending in the answer sheets had a higher error level than those that were not, but no difference was found. Finally, the preliminary results regarding the accuracies of various methods of antibody screening are presented. Although there was a statistically significant difference in the results obtained with the different methods, the study does not involve enough antibodies at this time to be valid, and therefore it will be continued.
