This study was retrospective aimed to study the correlation between the transcutaneous bilirubin meter JM-105® and serum bilirubin levels (TSB) and to evaluate the accuracy of the JM-105® transcutaneous bilirubin meter compared to micro-bilirubin measurements in blood, using TSB as the gold standard. The population are consisted of 320 newborns admitted to King Narai Hospital between January 1, 2023, and December 30, 2023. The instruments used included data recording forms, which captured the infants' basic information and bilirubin level measurements. Data were analyzed using descriptive statistics, Chi-square, t-tests, correlation coefficients, and predictive capability assessments.
Results: Of the 320 newborns, 170 underwent micro-bilirubin measurement in blood, and 150 underwent transcutaneous bilirubin (TcB) measurement. The majority of the participants were female, and there were no significant differences between the characteristics of the two groups. TcB levels showed a good correlation with serum bilirubin levels (r = 0.72). The predictive performance of the transcutaneous cut off level 13 mg/dL measurement compared to blood measurement yielded values for sensitivity, specificity, negative predictive value, and false positive rate, 97.9, 62.5, 83.3, 16.6 respectively.
