CAP comprehensive blood bank survey--1985

Approximately 2800 laboratories participate in the voluntary Comprehensive Blood Bank Survey of the College of American Pathologists, including graded challenges relating to ABO and Rh typing, antibody detection and identification, and crossmatching. The Surveys have shown consistently good performance in these areas. Ungraded responses reporting results of antigen typing, other cell or serum challenges selected for educational value, and supplemental questions are reviewed. The supplemental questions are designed to elicit practice patterns and to present opportunities for educational comments in the critiques.
