ABO and Lewis Blood Grouping with ABH Secretor and Non-secretor Status: A Cross Sectional Study in Dhaka

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.
