A month ago a new employee, had a negative antibody screen on a patient with a historical Anti-E. He did not screen the units he set up for her. She got one E positive unit. Before the second unit was issued a second CLS caught the error and screened for E negative units. We checked the patient at 1 week post, 2 week post, and 1 month for visable hemolysis, direct and indirect coombs. She continued to remain negative. We still had to report this to the FDA #QC-93-11. The hospital he worked before us did not keep antibody histories. It can be scary out there. AntRita
