ABSTRACT
Introduction: The ABO and Rh blood group systems are themost important blood group systems in Transfusion Medicine.This study was carried out with an objective to study thedistribution of ABO and Rh blood groups among voluntaryblood donors in Central Gujarat, India which is essential foreffective management of blood inventory.Material and Methods: The present retrospective studywas carried out at our blood centre. The data of presentstudy is from 01/06/2009 TO 31/12/2019. Total 398803voluntary blood donors were considered medically fit andaccepted for blood donation. ABO and Rh typing was doneby Manual Microplate Technique (June 2009 to August 2015)and automated blood group Immucor Galileo neo machine(September 2015 to December 2019) both forward and reverseblood grouping after validation at blood bank.Result: Out of 398803 blood donors B blood group was mostcommon(143408-35.96%) and the least blood group was ABBlood group (33631 – 8.43%). There were more Rh Positiveblood donors (372660 – 93.45%) as compared to Rh Negativeblood donors (26143 – 6.55%).Conclusion: The most common blood group among voluntarydonors was B positive and least common blood group was ABnegative.
ABSTRACT
A cross sectional study was done with 42 apparently healthy persons aged 6 years and above from both sexes. Most of them are blood donors in the department of Transfusion Medicine, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Few, other than blood donor, were selected from the same locality. Five ml venous blood was collected with all aseptic precautions. ABO blood grouping and Lewis phenotyping were done by tube method. ABO reverse grouping was also done from serum. With all precautions 2 ml of saliva was collected from all subjects. Secretor status was detected from the saliva by haemagglutination inhibition method. ABO blood grouping shows 36% 'O' group, 24% 'A' group, 33% 'B' group and 7% 'AB' group. Distribution of Lewis phenotype are Le(a+b-) 19%, Le(a-b+) 53%, Le(a-b-) 26% and Le(a+b+) 2% only. 60% of study population was ABH secretor and 40% non-secretor.
