Hi All, I hope someone can help me with some clarification. I was reading about the presence of H antigens in different ABO blood group patients, but I am getting different answers depending on what I read. Transfusion Medicine and Hemostasis- Clinical and Laboratory Aspects- 2nd Edition mentions O > A2 > B > A2B > A1 > A1B with O having the most, whereas BBTS Introduction to Transfusion Practice-6th edition mentions O > A2 > A2B > B > A1 > A1B. Maybe it doesn't really have a big impact to my routine work, but it is still good to be in the know. Any thoughts would be welcome. Regards, Jermin
What are other people's institutions practices on the following. If you have a patient with an anti-D do you need to go ahead and carry out the D antigen typing on the patients rbcs through the IAT phase(weak D testing)? The AABB 18TH ed. Technical Manual states on pg. 327 "When the D type of a patient is determined, a weak D test is not necessary except to assess the red cells of an infant whose mother is at risk of D immunization." It then goes on to say under Identification of Antibodies to Red Cell Antigens pg.401 "Determining the phenotype of the autologous red cells is an important part of antibody identification." We use MTS gel for as our primary method for blood type determination and it states that Most weak D antigen expressions will be detected(which means not all), however partial DVI epitope variant of the D antigen will not be detected with this monoclonal reagent. Not that it really changes how we transfuse the patient but just curious to others procedures/thoughts. Thanks in advance.
