Objective: To determine the diagnostic accuracy of cord blood bilirubin in predicting neonatal hyperbilirubinemia, taking neonatal hyperbilirubinemia within one week of birth as the gold standard.
Study Design: Across-sectional study.
Place and Duration of Study: The Study was conducted at the Department of Pediatric Medicine, Sheikh Zayed Hospital, Rahim Yar Khan, Pakistan from 7th September 2020 to 6th March 2021.
Methods: A total of 366 term neonates of both genders were included. Neonates with congenital hypothyroidism, neonatal hepatitis, biliary atresia, and sepsis were excluded. After getting informed consent from parents, a cord blood sample was taken and sent to the institutional laboratory for measuring total bilirubin levels, and neonatal hyperbilirubinemia (yes/no) was noted. All neonates were followed by the researcher for one week and neonatal hyperbilirubinemia was noted.
Results: The study yielded 193 true positive and 14 false positive cases, along with 7 false negative and 152 true negative cases, with a statistically significant p-value of 0.0001. Overall, the diagnostic accuracy of cord blood bilirubin in predicting neonatal hyperbilirubinemia, using neonatal hyperbilirubinemia within one week of birth as the gold standard, was found to be 96.50% for sensitivity, 91.57% for specificity, 93.24% for positive predictive value, 95.60% for negative predictive value, and 94.26% for diagnostic accuracy.
Conclusion: This study has shown that cord blood bilirubin has a rather good diagnostic accuracy for predicting newborn hyperbilirubinemia.
