New transcutaneous jaundice device with two optical paths
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).
