An age-dependent ABO discrepancy between mother and baby reveals a novel A(weak) allele.

Transfusion - 1 Feb 2015

Abstract excerpt

BACKGROUND: Discrepancies in ABO grouping arise due to different reasons, posing a threat to patient safety. Underlying causes include mixed-field agglutination after transfusion, chimerism, fetomaternal exchange, or inheritance of unusual alleles resulting in weak A/B antigen expression. Cord blood from the infant of a group A2 B mother typed as group O, H+. Samples were investigated to elucidate this conundrum....
