Detailed explanation-1: -72 hour rule A blood group and antibody screen expires 72 hours after collection. A fresh blood group and antibody screen will be required for any units not commenced within the 72 hour period. The time and date of collection of the cross match specimen is indicated in the Electronic Medical Record (EMR).
Detailed explanation-2: -Irregular antibodies are antibodies found in the blood of transfusion donors that have the potential to cause hemolysis of the recipient blood. Screening using an indirect Coombs Test should be performed to ensure that the donor blood is compatible with the recipient.
