The publication by Mandal et al. on the correlation between transcutaneous bilirubin (TCB) estimation and total serum bilirubin (TSB) estimation in neonatal hyperbilirubinemia in Indian infants was really interesting. The authors found a strong agreement between TSB and TCB in the term population as well as the whole population. Based on their study results, the authors recommended that all normal infants be screened for hyperbilirubinemia initially by measuring their TCB levels. If TCB reading is above the 75th percentile for age, it could then warrant for TSB level estimations. The authors addressed some limitations that might cast some suspicions on the study results and recommendation. I assume that the following four limitations could be further relevant.
First, the authors conducted their study in a single-tertiary center. Therefore, the results could not be generalized to other centers across the country. Large-scale multicenter studies are needed to verify the aforementioned findings and recommendation.
Second, the authors mentioned that TCB readings were done using Konica the Jaundice Meter JM-103 device (manufactured by Draeger Medical Systems, Inc., Lubeck, Germany). It is explicit that there are many different TCB meters in the clinical field to measure TCB and various agreement of TCB with each other and TSB has been reported.
Third, to my knowledge, the Indian population is a unique amalgamation of diverse races and different grade of skin discoloration. I assume that the diverse racial standards of the studied cohort might change the accuracy of the study results. This is based on the observation that TCB bias could be influenced by the race when estimation was done on the forehead, but not when it was done on the sternum.
Fourth, the accurate evaluation of TCB measurement in the neonatal nursery relies upon the hour-specific, percentile-based TCB nomogram. Specific TCB nomogram is not yet built for Indian neonates. The authors employed in the study methodology the American bilirubin nomogram that are specific for American neonates. This ultimately might render interpretation of the reported TCB readings in the study questionable.
