Immunoglobulin M anti-A and anti-B titers in South Texas group O D+ male donors.

Background: The success of whole blood (WB) in damage control resuscitation on the battlefield has generated interest in its use for civilian trauma. Blood centers must maintain a committed donor pool with low isoagglutinin titers to provide this product. Information regarding isoagglutinin titers in different donor populations will help with targeted recruitment of these donors.

Red cell antigen prevalence predicted by molecular testing in ethnic groups of South Texas blood donors.

Alloimmunization to red blood cell antigens is seen in patients receiving chronic blood transfusion. Knowing the prevalence of blood group antigens of the different ethnicities of South Texas donors can provide better management of rare blood inventory for patients in this geographical area. A total of 4369 blood donors were tested and analyzed for various antigens in the following blood group systems: ABO, Rh, Kell, Duffy, Kidd, MNS, Lutheran, Dombrock, Landsteiner-Wiener, Diego, Colton, and Scianna.
