This study aimed to assess the accuracy of transcutaneous bilirubin measurements in term and late-preterm infants undergoing phototherapy. Transcutaneous bilirubin levels were measured from different anatomical sites during and after treatment, and compared to total serum bilirubin levels. The agreement between the two methods was evaluated using Bland-Altman plots.

This study focused on evaluating the accuracy of transcutaneous bilirubin measurements in term and late-preterm infants who were receiving phototherapy treatment. Transcutaneous bilirubin levels were measured at two different locations - the glabella (forehead) and lower abdomen - while the infants were undergoing phototherapy. These measurements were then compared to total serum bilirubin levels, which is the gold standard for assessing bilirubin levels in the blood.

The researchers used Bland-Altman plots to analyze the agreement between the transcutaneous bilirubin measurements and total serum bilirubin levels.

By comparing the transcutaneous bilirubin measurements to total serum bilirubin levels using Bland-Altman plots, the researchers were able to determine the accuracy of the transcutaneous measurements in this specific population of infants undergoing phototherapy. This information is important for healthcare providers to ensure that they are using the most accurate and reliable method for monitoring bilirubin levels in infants receiving treatment for jaundice.
