In 2007, Milkins (22) described, in a report of the UK National External Quality Assessment Scheme (proficiency testing) data, (23) that technology used for grouping and screening had shifted from tubes and liquid-phase microplates to gel technology, with 65% of participants using gel methods for ABO grouping and 90% using gel methods for screening.
Among useful problems are identification of atypical red blood cell antibodies, unusual requests for blood components (or requests for unusual blood components), mismatched forward and reverse ABO groupings, transfusion reaction workups, mislabeled pre-transfusion blood specimens, and nettlesome decisions regarding blood component inventory.
