The predictive significance of umbilical cord bilirubin and bilirubin/albumin ratio for neonatal jaundice in healthy term newborns

Background/aim: The aim of this study is to determine the value questions asked in routine follow-up, cord blood bilirubin (CBB) and bilirubin/albumin (B/A) ratio estimating risk developing hyperbilirubinemia. Materials methods: Term healthy 217 newborns whose CBB albumin could be obtained needed measured level at 24th 72nd hours life were included. Nutrition, sex nationality, consanguinity between parents, jaundice sibling (s), mother's medications questioned. albumin, serum total (STB), transcutaneous (TcB) life, recorded. Results: B/A ratio, STB TcB found higher babies who received phototherapy (p < 0.001 for all). moderate positive correlation (correlation coefficient 0.383) hour strong 0.759) measurements was detected. In need sensitivity specificity 74.2% 56.5%, specifity 74.2%, 61.8%. cut-off 1.8, 0.56. When 1.8 CCB 0.56, predictive values are low, but negative significantly high (92.9% 93.5%, respectively) determining phototherapy. Conclusion: important predicting possibility indirect hyperbilirubinemia (IHB) development. Babies should followed closely terms IHB development when their mg/dL above, 0.56 above.
