Is it easy to miss Bombay blood group? A case report

Bombay blood group is clinically significant blood group as it not compatible with other blood groups, such as A, B, AB, and especially the O type. Transfusion with any other blood group can lead to fatal hemolytic transfusion reactions. This is a case report where Bombay blood group was misdiagnosed as O blood group despite performing forward and reverse blood group on a gel card (column agglutination Technique). While performing, reverse grouping reaction with O cells was not checked as it was not present in the gel card. A simple test like blood grouping should be done with serious intention with incorporation of both forward and reverse grouping (with A, B and O cells), so that no patient receives wrong blood leading to fatal hemolysis due to transfusion.
