Abstract:
Background:The ABO blood group system was the first human blood group system to be discovered by Landsteiner in 1900.The second type of blood group is the rhesus system.There are only two Rh phenotype such as Rh positive and Rh negative, depending on whether Rh antigen is present on the red cell or not.The frequency of ABO and Rh phenotypes in different populations has been extensively studied.The present study was done to assess the prevalence of blood groups in different categories of Northern India and to compare our results with other studies conducted in India and else where in the world and its multipurpose future utilities for the health planners.Methods: A retrospective study was carried out on 23,320 blood donors during a period of one year from 1 st January to 31 st December 2011.The Blood samples were obtained by standard procedures of venupuncture and subjected to determination of ABO and Rhesus blood group using antisera by combined slide and test tube method.Each sample of donors was tested for ABO and Rhesus status. Results:The blood group B (34.84%) was the commonest group prevalent in donors followed by group O (29.75%),A (21.50%) and AB (13.91%).AB negative was not seen in female donors. Conclusion:The commonest ABO blood group was group B in Northern India with Rh negativity at only 4.55%.Keywords:

Abstract Background and Objectives. This study was conducted to form a better understanding of the distribution of ABO and Rh types among the population of the north of Asir region in Saudi Arabia and compare the findings to similar studies that were carried out in other parts of the kingdom and the Middle East. Understanding the frequency of different blood types in different populations is imperative. Blood types are essential not only for transfusion therapy but also for the prediction of the outcome of different diseases. The study aims to establish an understanding of the blood group frequency among the residents of the north of Asir region, Saudi Arabia. Additionally, this study was conducted to compare the blood group frequency in the region to that in different parts of the Arabian Peninsula. Subjects and Methods This study was done throughout 1year from January 1, 2020, to December 31, 2020, using samples from 4142 voluntary subjects at the blood bank of King Abdullah hospital, Bisha. Commercially provided ABO and Rh antibodies were used for the standard blood grouping procedure. Results: Our findings have shown that O is the most prominent ABO blood group while AB was the least frequent. The frequency of A blood type was the second high followed by B blood group while positive Rh factor was more common than the negative. A Comparison of our findings to other studies from Saudi Arabia and nations in the Middle East was also discussed. Conclusion: O+ >A+ >B+ > O->AB+> A->B- > AB- is the order of blood groups frequency in our study for males, while in females the order was almost the same except for the last three blood types was as following: >A->B->AB+. AB- on the other hand, was completely absent in female donors. There are some similarities and differences between our findings and that of other studies from the kingdom and other countries. Knowing and understanding the distribution of ABO and Rh types is essential for creating better policies for transfusion interventions and blood banks managements.

Introduction: Blood grouping is one of the essential aspects of blood transfusion practice. ABO and Rhesus (Rh) blood groups are the two most important blood group systems among the various types identified so far. Distribution of ABO blood group varies indifferent geographical and ethnic groups. Objectives: This study was carried out to determine the distribution pattern of blood groups among blood donors at a tertiary care hospital of Southern Rajasthan. Methods: It is a retrospective study covering a period of 3 years from July 2014 to June 2017 that includes 3718 blood donors of which 1297are voluntary and 2421are replacement blood donors. Data on the ABO and Rh blood group type of all blood donors was collected and analysed. Result: The most common ABO blood group type was Group B (36.6%) followed by group O (32.1%), group A (22.8%) and group AB (8.5%) respectively. The distribution of Rh(D) blood group type revealed 93.5% as Rh-positive and 6.5% as Rh-negative. Conclusion: The most common ABO blood group type in our region (Southern Rajasthan) is Group B followed by O and A while, AB is the least common type. Knowledge of the blood group distribution pattern is essential for the effective delivery of blood banking services.

The ABO blood group system is used to denote the presence of one, both, or neither of the A and B antigens on erythrocytes. In humans, this is the most important of the 43 different blood type (or group) classification systems currently recognized. Distribution of ABO and Rh among the Saudi population could affect many factors such as blood transfusion, prognosis, resistance and susceptibility to diseases. The impetus of this study was to develop an understanding of the distribution of the ABO and Rh types of healthy volunteer blood donors in the northern Asir region of Saudi Arabia, comparing the findings to similar studies. Understanding the frequency of different blood types in different populations is imperative.This study was performed during the period of January 1, 2020, to December 31, 2020, using samples from 4167 voluntary subjects obtained from the blood bank of the King Abdullah Hospital, Bisha. Commercially provided anti-A, anti-B and anti-D antibodies were used for the standard blood grouping procedure.The findings in this study showed that O was the most prominent ABO blood group, whereas AB was the least so. The frequency of the blood type A was the second highest, followed by the blood group B, whereas Rh positivity was more common than Rh negativity.O+ > A+ > B+ > O-> AB+> A-> B- > AB- was found to be the order of blood group frequency in the current study.

BACKGROUND: ABO blood grouping is now regarded as one of the most important immunological tests to do before numerous treatments, including clinical blood transfusion operations. The purpose of this study was to record the different blood types among the people of southern Babylon, Iraq, and compare the findings for males and females. METHODS: A total of 10,570 subjects, of which 6643 were females, and 3927 were males, were involved in this study from February 2, 2022, to June 1, 2022. The antigen-antibody agglutination test was used to determine blood type and Rh factor. For both males and females, the frequency of each kind was determined. RESULTS: The blood group O was the most common among the investigated population in all areas and among both sexes, followed by blood groups B and A, with the B group somewhat higher among females and the A slightly higher among men. The AB blood group was the least common of the four. Blood type B was prevalent in females (26.97%) compared to males (24.41%). Whereas blood type A was more prevalent in males (24.59%) compared to females (24.12%). CONCLUSIONS: Positive Rh+ (antigen D) was observed in 9492 (89.8%) of all participants, whereas Rh negative in 1078 (10.2%). Prevalence of blood O positive was more predominant in females than in males (40.77% and 28.69%, respectively). Group AB positive was more predominant in males than in females (14.8% and 7.48%, respectively).

ABO blood group system is of significant identified by Karl Landsteiner. ABO typing involves both antigen typing and antibody detection. Gene for allele-I is present which determines blood group type. Further, differentiation of blood group takes place by Rh factor. Blood group type also effect on person interests toward different things including games. 180 students took part in study that how blood group type effect on trend toward games and results were different for each blood group.
