ABO and Rhesus (D) Blood Group Distribution among Blood Donors in Rural South Haryana (Mewat-Region): A 5 Years Retrospective Study

Background: In India, geographical distribution of blood groups and Rhesus (D) factor varies across the country. The aim of this study is to examine the distribution of these groups among voluntary blood donors at a large academic medical centre; SHKM which is situated in a rural, most backward, least literate, remote pocket of south (Mewat-region) Haryana state in India. Methods: A retrospective study was conducted using 5 year data (August 2013–December 2017) from a regional blood bank in rural south (Mewat-region) Haryana of India. Records of 16,121 voluntary blood donors were reviewed. Results: The distribution of ABO blood group was; blood group O (29.69%); blood group A (22.37%); blood group B (37.72%) and blood group AB (10.22%). A significantly higher proportion of Rhesus (D) positive than Rhesus (D) negative in blood group A and AB (respective p-values are .018 and .089). Conclusion: The sequence of ABO distribution among the rural population in south (Mewat- region) Haryana of India is; B > O > A > AB, with males as the predominant donors.
