Objectives: To confirm the accuracy and precision of transcutaneous bilirubin (TcB) values measured by a new device with two optical paths (JM-103) and the value of total serum bilirubin (TSB) level in clinical units of measurement.
Methods: For comparison of the levels of accuracy and precision of JM-103 and the old device (JM-102), serum samples were collected from 77 Japanese infants in three different hospitals including 24 preterm infants and 53 term infants. Measurement of TcB by JM-103 and JM-102 were performed on the forehead of each infant within 30 min before or after blood sampling.
Results: The range of TSB was limited to 19.6 mg/dL and to 17 mg/dL for preterm infants. The correlation coefficients for all subjects (r = 0.94) and for term and preterm subjects between TcB measured by JM-103 and TSB was higher than that between TcB measured by JM-102 and TSB. The regression line in term infants between TcB measured by JM-103 and TcB was similar to that in preterm infants. The error distribution of TcB measured by JM-102 and TSB for all subjects (0.00+/-2.21) and for term and preterm subjects was larger than that of TcB measured by JM-103 and TSB (all subjects, 0.30+/-1.55).
