The ABO blood groups of mothers and infants requiring EBT Maternal ABO blood groups against infant’s ABO blood groups and possible incompatibilities are shown in Table 2. The common ABO incompatible groups were mother O/infant B (30/57; 53%), mother O/ infant A (17/57; 30%) and mother B/infant A (4/57; 7%). Eighteen of the 57 (32%) infants who had ABO incompatible were Coomb positive, with 37% of the mother O/ infant B and 23% of mother O/ infant A having positive Coombs.
