OBJECTIVE: To verify the usefulness of the BiliCheck transcutaneous bilirubin meter as a screening device for neonatal jaundice in a Chinese population compared with the Minolta bilirubin meter.
DESIGN: A prospective correlation study that compared transcutaneous bilirubin measurements with serum bilirubin levels.
SETTING: Obstetric ward and a neonatal unit of a regional hospital in Hong Kong.
PATIENTS: Neonates with gestation above 32 weeks with neonatal jaundice who were admitted between April 2001 and February 2002.
MAIN OUTCOME MEASURES: Transcutaneous measurements of serum bilirubin obtained from the forehead and the sternum with two instruments: BiliCheck and Minolta Airshields JM 102.
RESULTS: A total of 77 term and six near-term babies (gestation, 32-37 weeks) were recruited. The mean age at the time of data collection was 3.96 days (range, 2-9 days). The correlations between serum bilirubin and transcutaneous bilirubin measurements of the two devices at the two sites were high, with a coefficient of 0.718 (95% confidence interval, 0.610-0.800; n=100) for forehead measurements, and 0.814 (95% confidence interval, 0.740-0.870; n=99) for sternum using the Minolta Airshields JM 102; and a coefficient of 0.757 (95% confidence interval, 0.657-0.827; n=98) for forehead measurements, and 0.794 (95% confidence interval, 0.700-0.862; n=92) for sternum using the BiliCheck. For BiliCheck, a cut-off point of 250 micromol/L at the forehead and 260 micromol/L at the sternum had a specificity of 61.9% and 70.0%, respectively with a sensitivity of 100% for the detection of serum bilirubin concentrations of 250 micromol/L or higher. This level is commonly used as the level for initiation of treatment such as phototherapy.
CONCLUSION: BiliCheck is a useful screening tool for neonatal jaundice in the Chinese population and is comparable with the Minolta Airshields JM 102.
