Correlation between serum bilirubin and JM-105 and MBJ-20 transcutaneous bilirubinometer measurements
Description
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.
