Background: RhD-negative blood products are in chronic short supply leading to renewed interest in utilizing RhD-positive blood products for emergency transfusions. This study assessed parental perceptions of emergency RhD-positive blood use in children.
Methods: A survey of parents/guardians was conducted on their tolerance of transfusing RhD-positive blood to RhD-negative female children ≤17 years old at four level 1 pediatric hospitals.
Results: In total, 621 parents/guardians were approached of whom 378/621 (61%) completed the survey in its entirety and were included in the analysis. Respondents were mostly females [295/378 (78%)], White [242/378 (64%)], had some college education [217/378 (57%)] and less than $60,000 annual income [193/378 (51%)]. Respondents had a total of 547 female children. Most children's ABO [320/547 (59%)] and RhD type [348/547 (64%)] were not known by their parents; of children with known RhD type, 58/186 (31%) were RhD-negative. When the risk of harm to a future fetus was given as 0-6%, more than 80% of respondents indicated that they were likely to accept RhD-positive blood transfusions on behalf of RhD-negative female children in a life-threatening situation. The rate of willingness to accept emergent RhD-incompatible blood transfusions significantly increased as the potential survival benefit of the transfusion increased.
Conclusion: Most parents were willing to accept RhD-positive blood products on behalf of RhD-negative female children in an emergency situation. Further discussions and evidence-based guidelines on transfusing RhD-positive blood products to RhD-unknown females in emergency settings are needed.

Introduction: Weak D red cells were defined as having a reduced amount of D antigen (formerly called "Du") that required an indirect antiglobulin test (IAT) for detection. Weakly reacting D is those which give <2+ reactions on routine methods. The present study is sharing our experience on weak D and weakly positive anti-D in various methods.

Background: Although ABO and RhD are the clinically significant blood group antigens that are routinely tested for, other blood group antigens may become important in multiply transfused patients due to risk of alloimmunization. Knowledge of antigen prevalence in a population is important in the context of alloimmunization and antigen matching. This study aims to do the same in a population of voluntary blood donors of a center in South India.

The traditional approach to resuscitating injured women of childbearing potential (WCBP) with an unknown RhD type is to transfuse RhD-negative blood products. This is to prevent alloimmunisation to the RhD antigen and ultimately prevent haemolytic disease of the fetus and newborn (HDFN) in future pregnancies should she survive. RhD-negative blood products are scarce in both military and civilian blood stocks.

Background and objective RhD variants show altered D antigen expression, affecting their serological detection. Proper identification is crucial due to potential anti-D antibody formation. This study aimed to retrospectively analyze the frequency and characteristics of D variant cases encountered during RhD typing in both blood donors and recipients and the transfusion implications.

Objective: To investigate the cause of the production of anti-D and anti-E mixed antibody in an RhD positive patient.
Methods: The ABO/Rh blood group typing and irregular antibody specificity were identified by conventional serological methods, the gene exon 1-10 and heterozygous analysis were performed by sequence-specific primer polymerase chain reaction (PCR-SSP), and the whole exon sequence was analyzed by first-generation sequencing.
Results: The patient's Rh blood group was weak D Type33, with the allele was , the patients was found to be heterozygous, with an Rh typing of Ccee, and the patient had developed anti-D combined with anti-E mixed antibodies.
