A Case of Ael with Anti-A / 대한수혈학회지

ABSTRACT

We report a case of Ael in a 44-year old woman. The patient' red cells were typed as O and her serum had both anti-A and anti-B, but the agglutination strength with A1 cell was weaker (2+) than with B cell (4+) in her serum. Additional tests showed that the red cells were not agglutinated by anti-A,B and A antigen on patient' RBC was demonstrated by adsorption-elution test. Her saliva contained H but no A substance, and the ABO genotyping test identified her blood type as AO. We concluded that this was a case of blood type Ael with anti-A.
