Our P & P states: " Testing will be performed on cord blood samples as ordered. An antibody Screen and Quick Screen (A1 cells and B cells tested with the patient's plasma/serum at the antiglobulin phase) will be performed on all samples with a positive direct antiglobulin test (DAT) if the Quick Screen does not demonstrate an antibody that would explain the positive DAT perform an elution. We usually could explain the DAT positive if Mother ABO is incompatible with the baby performing a "Quick Screen". We received a suggestion for others Blood Bankers to eliminate the Quick Screen and perfom Lui Easy Freeze Elution on ALL samples with DAT positive. What are you doing with Cord Blood samples with DAT positives? Quick Screens and Lui as needed? or Lui Easy Freeze Elution on all samples?
