The direct antiglobulin test (DAT) can identify infants developing hemolytic disease. This study aims to evaluate the significance of DAT positivity among neonates with ABO incompatibility.<\/jats:p><jats:p>\n            Study Design\u2003This retrospective study included 820 neonates with blood group A or B who were born to blood group O mothers. The study group consisted of neonates (n\u2009=\u200979) who had positive DAT, and the control group consisted of infants (n\u2009=\u2009741) who had negative DAT. Demographic and clinical data of the neonates regarding jaundice were collected and compared statistically.<\/jats:p><jats:p>\n            Results\u2003The bilirubin level at 24\u2009hours of life (study group: 8\u2009\u00b1\u20092.6\u2009mg\/dL, control group: 6\u2009\u00b1\u20092.2\u2009mg\/dL, p\u2009&lt;\u20090.001) and the highest bilirubin level (study group: 12.7\u2009\u00b1\u20093.6\u2009mg\/dL, control group: 10.4\u2009\u00b1\u20094.2\u2009mg\/dL, p\u2009&lt;\u20090.001) were higher in infants with positive DAT. A total of 37 (46.8%) infants in the study group and 83 (11.2%) infants in the control group received phototherapy (PT) in the nursery (p\u2009&lt;\u20090.001). In neonates with positive DAT, direct bilirubin level, duration of hospitalization, and PT in the nursery were higher (p\u2009=\u20090.002, &lt;0.001, and &lt;0.001, respectively), whereas hemoglobin level was lower (p\u2009&lt;\u20090.001).<\/jats:p><jats:p>\n            Conclusion\u2003In neonates with ABO incompatibility, a positive DAT is a risk factor for developing significant hyperbilirubinemia. Close follow-up of newborn infants with ABO incompatibility is crucial for early detection and treatment of neonatal jaundice to avoid early and late complications.<\/jats:p><jats:p>\n            Key
