Principle:
Organ donors with a history of RBC transfusion within the past three months must have ABO subgroup (weak A as detected by A2 cells and anti-A1 lectin) if the transfusion included group A RBCs.
Policy:
- Organ donors who are typed as A should be tested to distinguish group A1 from weak subgroups of A.
- Use anti-A1 lectin and A2 cells as indicated.
