Factor VIII (antihemophilic factor) assay results in the 1976 College of American Pathologists Survey Program.
Data from the 1976 CAP Survey for the performance of Factor VII (antihemophilic factor) assays were analyzed. The results indicated an undesirable variation on both normal and abnormal specimens. Reagent-instrumentation systems and procedures were examined. The need for standardization of factor VIII assays is evident from the results of this study.
