Expression of strong IgM type Anti H in Bombay phenotype cases can lead to acute intravascular hemolytic reactions if they are transfused with ABO group O negative blood.
Case
Our case had been recognized as blood group O with Negative Rh. In his recent donation, during antibody screening a high titers of anti A, anti B, and anti H were detected. In addition, there was no agglutination when donor's RBC and anti H were mixed. There were no Kell and CDE in the sample and the Rh genotype was recognized as cde/cde (rr).
Conclusions
According to Oh phenotype reports, the number of Bombay phenotype is 6 in Esfahan and 15 in Iran. It seems that antibody screening should be further considered in Esfahan.
