Proportion of Rh phenotypes in voluntary blood donors

Abstract

a b s t r a c tBackground: The Rh system is the major blood group system besides ABO system. Even after proper blood grouping and cross matching there is a possibility of alloimmunization and antibody production in the recipients against the Rh or minor blood group antigens like Results: The phenotypic frequencies of Rh blood groups in the studied population were D-92.25%, C-87.55%, E-26.55%, c-51.06% and e-98.42%. Thus 'e' was the most common and E was the least common of all the Rh types. Phenotypically DCCee group was the most common phenotype and dccee was least common type.Conclusion: Determination of Rh phenotypes can play a major role in preventing alloimmunization and avoiding adverse events in multitransfusion cases.ª 2013, Armed Forces Medical Services (AFMS).

Phenotype Prevalence of Blood Group Systems (ABO, Rh, Kell) in Voluntary, Healthy Donors-Experience of a Tertiary Care Hospital in Delhi, North India

“…B blood group was found to be most common similar to other studies from India [8]. In Rh system D antigen frequency was found to be 93.8% which was comparable to other studies from India [9][10][11]. On the basis of expression of different antigen of Rh system most common phenotype was found to be of DCe/DCe (R1R1) //DCe/Ce (Rr) (44.7%) and similar findings by Agarwal (42.93%), Thakral et al (43.8%) and Sarkar (35.2%) [8,9,11].…”

“…Incidence of anti-D is very uncommon in country with low frequency of Rh (D) antigen. In Indian population due to relatively high prevalence of D negative, D typing is a must [11]. Among Rh minor antigens those are present less commonly in predominant phenotype alloantibody would be more common against them.…”

Prevalence of Rh Antigens among voluntary blood donors in Chennai, Tamil Nadu, India

“…In negative subjects, the most commonly seen predicted Rh phenotype in this study was ce (rr) which is similar to that reported in study by Thakral et al 6 In contrast ce/ce (rr) was the least common phenotype reported by Sarkar et al Thakral et al showed ce/cE as the rarest phenotype. 6,9 DCe/dce (R 1 r) 31.1% and Dce/dce (R 0 r) 22.9% were the most common phenotype reported in whites and blacks respectively.…”

Frequency of Rh Phenotypes in Voluntary Blood Donors

“…The prevalence of other Rh Antigens (C, c, E, e) among the study population was compared with that of other studies carried out in India at different regions 3,[11][12][13][14] and with other populations 2,15-17 as presented in (Table 5). …”
