Abstract
Monoclonal antibody (MoAb) therapy has been increasingly used in recent years for hematologic malignancies. The MoAbs anti-CD38 and anti-CD47 are immunoglobulins directed against epitopes that are highly expressed not only on cancer cells, but also on red blood cells (RBCs), as well as platelets. Additionally, producing an off-target effect interferes in pre-transfusion testing, having the potential to unchain hemolytic anemia. Blood banks must assure the availability and safety of blood products for patients in need. Thus, MoAbs have become a challenge for blood banks, since methods to overcome interferences must be adopted. Several strategies have been proposed to mitigate pan-reactivity in pre-transfusion indirect antiglobulin tests, such as the treatment of reagent RBCs with enzymes or reducing agents, allogeneic RBC adsorptions, and drug-specific neutralization assays. All of these have some kind of limitation. This review summarizes the interferences of MoAbs in pre-transfusion testing, focusing on the available strategies to mitigate them in order to provide a safe transfusion.
