Correlation between serum bilirubin and JM-105 and MBJ-20 transcutaneous bilirubinometer measurements
Anecdotal reports have raised the possibility of discrepancies between the measurements by the TcBs and the serum bilirubin measurements (SBR) and questioned their accuracy. Also, there is a lack of research on the diagnostic accuracy of the TcB devices JM-105 and MBJ-20 according to the area tested in late preterm and term neonates. We aimed to evaluate the correlation between SBR and two TcBs used on the forehead and chest. Results: The mean differences between the TcB measurements on the forehead and sternum and the SBR levels were similar for the JM-105 and MBJ-20. The greatest correlation was observed between the SBR measured using the two devices on the sternum. Both devices had high sensitivity and negative predictive values at SBR <230 µmol/L, and high specificity and positive predictive value at SBR ≥230 µmol/L.
