Abstract

Introduction: Rare Bombay phenotype was first reported in Bombay, India by Bhende and Bhatia in 1952. Bombay phenotype is characterized by absence of H, A and B antigens on red cells and in secretions, while plasma contains anti A, anti B and anti H. Genetically Bombay Oh phenotype individuals are termed as homozygous hh/sese.

Methodology: Blood grouping (ABO and RhD) was done in our blood bank by semi-automated Column Agglutination Technology (CAT) as well as Tube agglutination method and performed Adsorption Inhibition Test using saliva (tube method) for confirming secretor status.

Results: A young 21years male voluntary donor donated blood at our blood bank. The ABO Grouping and RhD typing with serum grouping Indicated Bombay Oh RhD Positive group. Further tests done were: Direct Coombs Test/Indirect Coombs Test by 3 cell panel and Adsorption Inhibition Test by using saliva, which confirmed the Bombay blood group.

Conclusion: To identify Bombay Oh Blood group we recommend complete immunohematology workup (Blood Group: Forward and Reverse with Auto control) using standardised agglutination technologies combined with saliva testing for secretary status (with controls).
