Abstract
Aims: To assess the accuracy of capillary gas bilirubin (Radiometer TBiL) compared to venous total plasma bilirubin (Roche TPB), and to evaluate the reliability of Radiometer TBiL in neonatal hyperbilirubinaemia treatment decisions.
Methods: A prospective study was conducted at a tertiary neonatal centre in Dublin, Ireland between December 2023 and May 2025. Paired Radiometer TBiL and Roche TPB measurements were obtained from 97 neonates requiring bilirubin assessment.
Results: Radiometer TBiL demonstrated high correlation with Roche TPB (r = 0.97, p < 0.0001), although Radiometer TBiL showed an overestimation, especially at bilirubin levels between 150 to 230 µmol/L. Bland-Altman analysis revealed a mean difference of -16.6 µmol/L with wide limits of agreement (-63.6 to 30.4 µmol/L). Kappa analysis (κ = 0.35, 95% CI: 0.14 - 0.55) showed fair agreement in treatment decisions, with a tendency for Radiometer TBiL to overestimate the need for treatment, but there was no significant underestimation.
Discussion: Radiometer TBiL offers a rapid and less invasive alternative for bilirubin screening and risk stratification in neonates, with high correlation to standard laboratory measurements. While a tendency to overestimate bilirubin levels may lead to overtreatment, the absence of significant underestimation suggests Radiometer TBiL is a safe tool for clinical decision-making. Larger studies are warranted to validate these findings and refine clinical thresholds.
期刊介绍:
Since its inception in 1867, the Journal of the Medical Association of Ireland and now in its present format, the Irish Medical Journal, has provided the medical community in Ireland with an invaluable service. As one of the leading biomedical publications in Ireland, it has sought to continue the education of medical students and postgraduates through scientific research, review articles and updates on contemporary clinical practices while providing an ongoing forum for medical debate. A measure of our stature is that we are listed in the Index Medicus and issued annually with a citation factor from the Institute for Scientific Information.
