Abstract excerpt

BACKGROUND: The Para-Bombay phenotype is characterized by H antigen partially or totally deficient on red blood cells and the presence of ABH substances in body fluids. METHODS: A patient with discrepant results in forward and reverse ABO phenotyping was further investigated by serological and molecular methods. RESULTS: Ortho gel and tube results showed weak A antigen expression and weak antibody reacting with A...
