Molecular RHD screening of RhD negative donors can replace standard serological testing for RhD negative donors.
This work aims to assess the value of a generalized molecular RHD screening strategy which could replace routine serological screening of weak D by indirect antiglobulin test. Three independent studies were performed at the two Blood Transfusion Services Berne and Zurich. Donors investigated were 652 RhD negative, but RhC and/or RhE positive, 17,391 mainly Rhccee, and 8200 with normal RhCcEe ph...
متن کاملInvestigation of Paternal RhD Zygosity by Two Molecular Methods among Blood Donors in Kurdistan Province, Iran
Background: RhD antigen system is the leading cause of hemolytic disease of the fetus and newborn (HDFN). Paternal molecular RhD zygosity test is valuable to decide on the use of anti-D immunoglobulin prophylaxis in Rh D-negative pregnant women. We aimed to investigate the paternal RhD zygosity by two molecular methods among blood donors in Kurdistan province, the west of Iran. We also compared...
متن کاملRHD positive among C/E+ and D- blood donors in Denmark.
BACKGROUND Many different partial and weak D types have been reported, and most of these are easily detected by serology. However, 17 Del types have also been described, with a very low expression of the D antigen, only detectable by absorption-elution techniques, and these may elicit the development of an anti-D. A genomic test of C/E+ and D- blood donors was initiated, to be able to categoriz...
متن کاملImpact of a confirmatory RhD test on the correct serologic typing of blood donors
BACKGROUND The RHD gene is highly polymorphic, which results in a large number of RhD variant phenotypes. Discrepancies in RhD typing are still a problem in blood banks and increase the risk of alloimmunization. In this study, the RhD typing strategy at a blood bank in Brazil was evaluated. METHODS One-hundred and fifty-two samples typed as RhD negative and C or E positive by routine tests (a...
متن کاملVariant RHD Types in Brazilians With Discrepancies in RhD Typing.
BACKGROUND The knowledge of D variants in patients and donors is important because anti-D alloimmunization can occur in some but not all individuals who express a variant RHD allele. Serologic distinction of RhD discrepancies is not always straightforward, which makes molecular analysis highly desirable. METHODS A group of 223 subjects, 129 patients, and 94 blood donors was identified and ana...
