Results Initial serologic testing performed by the IRL indicated that the patient was group A,
weak D positive with a negative direct antiglobulin test (DAT). Serologic phenotype testing …

Pre-transfusion laboratory tests include ABO and RhD typing, antibody screening test,
antibody identification test, and cross-matching. The objective of pre-transfusion testing is to …

Background: The phenomena of co-incidence of transfusion-induced allo-and
autoantibodies, blockage and/or loss of red blood cell (RBC) antigens are conspicuous and …

Background Rh antibodies produced by patients receiving Rh-matched RBC units may be
associated with inheritance of altered RH alleles or a result of altered Rh epitopes on donor …

Background We previously reported unexpected Rh antibodies in the plasma of patients
with sickle cell disease (SCD) that demonstrated common Rh specificities in the absence of …

Background and Objectives In the Rh blood group system, partial D, C, and e antigens are
well‐known, but a partial c antigen resulting in the production of alloanti‐c in a c+ individual …

Discussion Rh is one of the most important blood groups with highly immunogenic antigens
that are indicative of its vital role in clinical transfusion medicine [2]. The five common Rh …

Background The Rh system is the largest and most polymorphic blood group system. The
existence of a large number of RH alleles results in variant phenotypes that often complicate …

Delayed hemolytic transfusion reaction is difficult to prevent using an unexpected antibody
test performed prior to transfusion, and unlike acute hemolytic transfusion reaction, it occurs …

A patient with phenotype R (2) r and anti-C had a hemolytic transfusion reaction (HTR) with
hemoglobinemia and hemoglobinuria which occurred within 2 h of receiving an R, r …
