“…[13] Other studies in Africa show highest frequencies of group O of 48.62% and 49.10% by Ndoula et al and Hamed et al respectively. [14,15] The frequencies of blood group AB in these studies are higher than that of this study, 4.45% and 4.05% against 2.47% in this study.…”

Background: The ABO is a blood group system that is responsible for most blood transfusion reactions, transplant rejections and determining some forensic cases. The ABO and Rhesus blood group systems have been shown to show variations in different part of the world and race. Aim: The study is to show the frequency of ABO and Rhesus blood groups amongst blood donors in Lagos, Nigeria and confirm Hardy-Weinberg equilibrium. Methods: This is a two-year retrospective study of all blood donors from the two major tertiary health institutions in Lagos State between July 2004 and June 2006. Data from the blood bank records were extracted and analysed using SPSS version 20. Hardy-Weinberg equation was used to confirm if the population is in equilibrium. Results: In all, 11,911 donors were analysed and showed A+ 20.4%, A-0.97%, B+ 16.7%, B-0.87%, AB+ 2.2%, AB-0.17%, O+ 55.6%, O-3.1% and RhD positive frequency is 95.6%. The allelic frequency in this study is O -0.7631, A -0.1303, B -0.1066 and Rh -0.7786. There is no significant difference between the blood group distributions from the two institutions. Conclusion: Blood group O was the commonest blood group seen followed by group A. This is at variance with other studies in Nigeria where blood group B was the second commonest. The population was also found to be in Hardy-Weinberg equilibrium. The study provides important and reliable genogeographical information that can advance the fields of blood transfusion, organ transplantation and forensic medicine in Nigeria.

“…Garratty et al reported that the total percentage of Rh‐D‐negative individuals was 14.6% among donors in the USA, varying from 1.7% in Asians to 17.3% in White non‐Hispanics . Hamed et al retrospectively analysed records from a 5‐year database containing ABO⁄Rh phenotype and ethnic origin of 10 116 volunteers that gave blood at the national blood transfusion centre in Mauritania and found that 5.77% of the Mauritanian population was Rh‐D and varied from 3.55% in Black Africans to 6.49% in Moors.…”

“…The ABO and Rh blood group systems are crucial in clinical transfusion and transplantation medicine . Previous data regarding the distribution of blood groups has mainly been obtained from blood donors, inpatients and pregnant women . The current large population‐based cross‐sectional study involved more than 3 800 000 Chinese adults from the general population and found that the largest proportion of participants had blood group A (30.54%), followed by O (30.37%), B (29.42%) and AB (9.66%).…”

ABO and Rh blood groups play a vital role in blood transfusion safety and clinical practice and are thought to be linked with disease susceptibility. The results from previous studies that focused on the association between blood groups and HBV infection remain controversial. China has the world's largest burden of HBV infection. We assessed the distribution of ABO/Rh blood groups in Chinese adults and examined the association between these groups and HBV infection. We did a nationwide cross-sectional study using data from a physical check-up programme from 31 provinces examined between 2010 and 2012. ELISA was used to test for HBsAg in serologic samples. Multivariable logistic regression was used to estimate aOR of the association between ABO and Rh blood groups and HBV infection. Among 3 827 125 participants, the proportion of participants with blood group A was highest (30.54%), followed by O (30.37%), B (29.42%) and AB (9.66%). A total of 38 907 (1.02%) were Rh-D negative. The prevalence of HBsAg in blood groups O, A, B and AB were 6.34%, 5.55%, 5.18% and 5.06%, respectively. HBsAg prevalence was 5.65% in Rh-D-positive and 3.96% in Rh-D-negative participants. After controlling for other potential risk factors, multivariate models showed that participants with blood group O (adjusted OR = 1.22, 95% CI: 1.20-1.25) were at higher risk of HBV infection compared with group AB. Rh-D-positive participants (adjusted OR = 1.44, 95% CI: 1.37-1.52) were at higher risk of HBV infection than Rh-D-negative participants. The associations between ABO/Rh blood groups and HBV infection were similar in subgroup analysis. The proportions of O, A, B and AB blood groups were approximately 3:3:3:1, and nearly 1 in 100 people was Rh-D negative among Chinese adults. Blood group O and Rh-D positivity were both associated with increased HBV infection. The risk of HBV infection and blood safety should be taken into consideration in clinical practice, especially when transfusing those with blood group O. Awareness and prevention of HBV infection is of particular importance for individuals with blood group O.

Objectives: To document the frequency of the ABO and Duffy blood groups antigens and phenotypes among Saudi population in eastern province. Methods: Hundred healthy individual adult have participated in this study (50 males, 50 females). Their blood was tested for ABO and for common Duffy antigens by using the tube agglutination method. Results: The O antigen was the most common antigen among the study group (39%), followed by A (35%), B (18%), and the least common antigen was AB (8%). The most common Duffy antigens were Fy a antigen (16%) and also Fy b antigen (16%). Regarding to Frequency of Duffy phenotypes, the phenotype Fy (a-b-) was the commonest Duffy phenotype (72%), followed by Fy (a+b-) and Fy (a-b+), and Fy (a+b+) was least common (4%).
