Antibodies against high frequency Gerbich 2 antigen (anti-Ge2): A real challenge in cross matching lab.

Transfusion management of patients' alloimmunized against high-prevalence erythrocyte antigens is often problematic in emergency situations. Gerbich (Ge) is very common blood group system and Gerbich-2 (Ge-2) antigen present in high frequency and outside Papua New Guinea population, Ge-2 negative population almost nil. To manage such kind of problems with real emergencies, implementation of rare donor registry program, cryopreservation of red cells of rare donors and biological cross matching to assess significance of these antibodies is warranted.
