Trends of ABO and Rh phenotypes in transfusion-dependent patients in Pakistan

The objective of this study was to determine the prevalence of ABO and Rh phenotypes in the general Pakistan population. This information could be used to help reduce the rate of alloimmunization in patients with blood disorders, such as thalassemia major, who require frequent blood transfusions. A total of 242 patients with blood disorders requiring frequent blood transfusions were enrolled in the study. ABO and Rh typing was performed on samples from these patients using tube and gel methods

Rh antigens and phenotype frequencies of the Ibibio, Efik, and Ibo ethnic nationalities in Calabar, Nigeria

This report forms part of the study on the Rh phenotypes within the various ethnic nationalities in the south-south region of Nigeria. The aim is to demonstrate the Rh polymorphisms among the people of African descent. The frequencies of Rh blood group antigens and phenotypes of the Ibibio, Efik, and Ibo ethnic nationalities in Calabar municipality, Nigeria, were determined using standard serologic techniques. Of the 720 Calabar individuals tested, the frequencies of the Rh antigens within the

A simple alternative for Rh phenotyping red cells that have a persistently positive Rh control

results were obtained when these modified cell samples were tested against Rh typing reagents from three manufacturers using a 37°C incubation followed by four saline washes. The procedure, termed Z37W, appears to be a simple alternative that can assist in determination of Rh phenotypes when the Rh control is positive.

Absence of hemolysis after a kidney transplant in an E+ recipient from a donor with anti-E

A 12-year-old Caucasian male with cystinosis received a kidney from his mother, whose red blood cells typed as group O, D+, E–. Her serum contained an anti-E with an IgG1 titer of 16 (score 31). The recipient’s type was group O, D+, E+, with a negative antibody screen in the pretransplant period. The recipient and donor Rh phenotypes were most likely DCcEe and Dccee, respectively. Because the recipient’s mother had no transfusion history, she was probably immunized by the

Rapid, single-subject genotyping to predict red blood cell antigen expression

isolated from fresh and 1- and 2-week-old stored blood from 20 donors with known ABO and Rh phenotypes and was used for ABO, RHD, and RHCE genotyping using SSPs.  The amplicons were analyzed using gel electrophoresis and a novel microfluidic onchip electrophoresis system.  Analysis of DNA from fresh and 1- and 2-week-old blood by SSP and gel electrophoresis yielded the correct ABO, RHD, and RHCE type in all samples, but with DNA from 2-week-old stored blood the amplicons were more difficult

Red blood cell phenotype prevalence in blood donors who self-identify as Hispanic

populations. We performed a retrospective review of all serologic and molecular typing from donors who self-reported as Hispanic. The phenotype prevalence was reported and compared with rates from other racial/ethnic groups. A total of 1127 donors who selfidentified as Hispanic were screened by serologic methods for Rh and Kell antigens, and 326 were subsequently selected for molecular typing. The most prevalent probable Rh phenotypes were R1r (26.6%), R1R2 (21.5%), and R1R1 (20.7%); rr was found in 7.8

Molecular characterization of GYPB and RH in donors in the American Rare Donor Program

Transfusion of patients with sickle cell disease (SCD) has been a challenge in clinical transfusion medicine, especially when the required donor RBCs must be U– and negative for high-prevalence Rh phenotypes (hrB,hrS). It is now possible to genotype donors to identify or confirm Uvar and U– phenotypes,as well as Rh hrB– and hrS– phenotypes,and to characterize the different RH backgrounds found in these donors. In a preliminary study of donors registered in the American
