ABO Subgroup Testing for Organ Donors

drzeyd

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:

  1. Organ donors who are typed as A should be tested to distinguish group A1 from weak subgroups of A.
  2. Use anti-A1 lectin and A2 cells as indicated.
