This study was undertaken from April 2002 to March 2003 to find out the correlation of transcutaneous bilirubinometer index with serum bilirubin levels in term, pre-term, small for gestation age babies, with and without phototherapy in neonates with jaundice. Another aim was to evaluate the transcutaneous bilirubinometer as a screening device for neonatal hyperbilirubinemia by finding the action levels for TcBI at forehead and sternum at which sample for serum bilirubin estimation should be taken. A total of 104 neonates were evaluated. Mean (SD) age (hours), birth weight (grams) and gestational age (weeks) were 100.4 (37.90), 2264.9 (634.4) and 36.8 (2.9) respectively. Mean serum bilirubin was 16.6 (6) mg/dL. Overall a correlation coefficient of 0.878 at forehead and 0.859 at sternum was observed. On excluding infants receiving phototherapy coefficients of 0.900 at forehead and 0.908 at sternum were noted. Correlation coefficient over forehead and sternum was found to drop from 0.85 to as low as 0.33 with duration of phototherapy exceeding 48 hrs. Lastly the determined action levels had a sensitivity of 77.8 to 100 % in assessing the need for serum bilirubin estimation in various groups.
