Use of LOR-15C9 monoclonal anti-D to differentiate erythrocytes with the partial DVI antigen from those with other partial D antigens or weak D antigens

Historically, red blood cells (RBCs) with partial D antigens have been defined serologically by their pattern of reactivity with polyclonal and monoclonal anti-D. Although numerous variants have been described in tests with well-characterized monoclonal anti-D, definition remains difficult to ascertain serologically. RBCs of known partial D type were tested with LOR-15C9 (a monoclonal anti-D) and commercial anti-D by the tube indirect antiglobulin test (IAT), by micro typing system IgG gel

Reactivity of FDA-approved anti-D reagents with partial D red blood cells

of IgM monoclonal anti-D blended with monoclonal IgG anti-D, one IgM monoclonal anti-D blended with polyclonal IgG anti-D, and two reagents formulated with human anti-D in a high-protein diluent. One antiD formulated for use by gel column technology was also tested. Direct agglutination tests by tube or gel were strongly positive (scores 9–12), with partial D RBCs of types DII, DIIIa, DIIIb, and DIVa. No reagent anti-D caused direct agglutination of DVI type 1, DVI type 2, or DFR phenotype

Incidence of weak D in blood donors typed as D positive by the Olympus PK 7200

The incidence of weak D has been reported to be between 0.23 and 0.5 percent in Europe and 3.0 percent in the United States. All studies were performed before the introduction of monoclonal anti-D reagents. Using current commercial reagents, this study evaluated D+ samples for the presence of weak D. D+ donors, typed by the Olympus PK 7200, using diluted monoclonal blend anti-D and diluted polyclonal anti-D, were selected by sampling batches of 100 to 200 samples from the previous day’s

Serologic and molecular characterization of D variants in Brazilians: impact for typing and transfusion strategy

with some monoclonal anti-D. Our results showed that the use of different methods and anti-D reagents in the serologic routine analysis revealed D variants that can be further investigated. Molecular methods can help to differentiate between partial D and weak D and to characterize the weak D types, providing additional information of value in the determination of D phenotypes. This distinction is important for optimized management of D– RBC units and for the prevention of anti-D&ndash
