Regarding hemoglobin concentrations in neonates with ABO
incompatibility, no significant differences were observed between
the control group and the indirect hyperbilirubinemia group, the
physiological jaundice group, or the early onset jaundice group.
However, the persistent jaundice group had significantly decreased
hemoglobin levels than the control group (11.0 6 1.4, p 5 0.01).
