Determining the Correlation and Accuracy of Three Methods of Measuring Neonatal Bilirubin Concentration|
Mussavi, Mirhadi; Niknafs, Pedram & Bijari, Bahareh
Objective: There are different methods for measuring bilirubin concentration; however, it is quite important
for practitioners to know which method should be used in certain clinical situations. The present prospective
study aimed to compare three different methods for measuring neonatal bilirubin concentrations.
Methods: All full term neonates who were either brought into emergency departments or admitted to the
neonatal wards in Kerman city in 2011 were recruited (n=428). The correlation coefficients were estimated
for the routine ways of bilirubin concentrations including "Capillary", "Cutaneous" and "Laboratory" methods.
Findings: Of 428 recruited neonates, 178 were female. Mean age ±SD was 178±71 hours. The correlation
coefficient for "David Icterometer" vs "JM103" was 0.91, while the corresponding coefficient for "David
Icterometer" vs "Capillary" was 0.96. It was also equivalent to 0.85 for correlation between "JM103" and
"Capillary" methods. The David Icterometer measured an average of 2.36 mg/dl levels of bilirubin
concentration compared to the JM103 method. The Capillary method showed a lower bilirubin level than the
venous concentration (0.91 mg/dl on average). Compared with the "Capillary", the "JM103" measured a
slightly higher level of bilirubin with an average 0.57 mg/dl.
Conclusion: Due to low difference (less than 1 mg/dl) between "JM103" and the "Capillary methods" for
measurement of neonatal bilirubin concentration, these two methods could alternatively be used instead of
usual laboratory method.
