Article Abstract
Background: Neonatal hyperbilirubinaemia (NH) is a common problem worldwide and is a cause of morbidity and mortality especially in low-resource settings.
Methods: A study was carried out at Shoklo Malaria Research Unit (SMRU) clinics along the Thailand-Myanmar border to evaluate a non-invasive test for diagnosis of NH in a low-resource setting. Performance of a transcutaneous bilirubinometer Dräger Jaundice Meter JM-105 was assessed against routine capillary serum bilirubin testing (with BR-501 microbilirubinometer) before phototherapy during neonatal care in the first week of life. Results were analysed by direct agreement and by various bilirubin thresholds used in clinical practice. Total serum bilirubin was also measured in cord blood at birth and tested for prediction of hyperbilirubinaemia requiring phototherapy in the first week of life.
Results: Between April 2020 and May 2023, 742 neonates born at SMRU facilities were included in the study. A total of 695 neonates provided one to nine capillary blood samples for analysis of serum bilirubin (total 1244 tests) during the first week of life. Performance of transcutaneous bilirubinometer was assessed in 307 neonates who provided 687 paired transcutaneous capillary blood tests. Bilirubin levels were also measured in 738 cord blood samples. Adjusted values of transcutaneous bilirubinometer showed excellent agreement with capillary serum bilirubin concentration (intraclass correlation coefficient=0.923) and high sensitivity (>98%) at all clinical thresholds analysed across 3 years of sampling and multiple users. Concentrations of bilirubin detected in cord blood were not useful in identifying neonates at risk of hyperbilirubinaemia requiring treatment.
Conclusions: The transcutaneous bilirubinometer is a reliable tool to screen neonates and identify those needing confirmatory blood testing. Bilirubin concentrations in cord blood are not predictive of hyperbilirubinaemia in neonates.

Background: Transcutaneous bilirubinometers provide a non-invasive method to estimate total serum bilirubin (TSB) using multiwavelength reflectance. However, their accuracy during phototherapy (PT) remains controversial due to decreased dermal bilirubin.
Objective: To assess the correlation between TSB and transcutaneous bilirubin (TcB) measured from covered and exposed skin areas before, during, and after PT.

Background: Preeclampsia is a complex, multisystem obstetric disorder characterized by heterogeneous clinical manifestations, often requiring enhanced strategies for early detection, management, and risk stratification. This study aimed to evaluate potential alterations in non-invasive transcutaneous bilirubin levels measured at various maternal body sites in pregnant women diagnosed with preeclampsia.
Methods: A total of 86 pregnant women who delivered at our institution were enrolled and classified into three groups: healthy pregnant women (Group 1, n = 30), women with preeclampsia (Group 2, n = 30), and women with pre-eclampsia with severe features (Group 3, n = 26).

Background: We recently reported that the transcutaneous bilirubinometer (TCB) tends to underestimate the severity of neonatal jaundice (NJ). We hypothesize that the cumulative ambient light exposure contributes to the discrepancy.
Objectives: This study aimed to identify factors that affect the TCB underestimation.

Background: Neonatal hyperbilirubinemia (NHB) is a significant cause of morbidity and mortality, particularly in low and middle-income countries (LMICs). Transcutaneous bilirubinometers offer a non-invasive method for assessing NHB but have limited availability due to cost and maintenance requirements. Visual assessment of jaundice is shown to be inaccurate.

Neonatal jaundice is a physiological phenomenon that occurs in newborns. However, because excess bilirubin can cause cytotoxicity, abnormal hyperbilirubinemia can lead to bilirubin encephalopathy. In the evaluation of neonatal jaundice, serum bilirubin concentrations are indirectly assessed via a transcutaneous bilirubinometer.
