Stool color along with transcutaneous bilirubinometer may help predict neonatal jaundice accurately:Study

Key findings of the study are:

-Out of 83 eligible neonates in the study, 15% had jaundice by 48 hours of age and 51% between 48-96 hours.

-From the analysis researchers found that the mean difference between Kramer scale and SBR was –3.2 mg/dL, between TcB and SBR was 1.6 mg/dL, and that between STrIP score and serum bilirubin was 0.9 mg/dL.

-On further analysis of Kramer, transcutaneous and STrIP score, method of bilirubin estimation against serum bilirubin, there was a mean difference 6 mg/dL, 4 mg/dL and 2 mg/dL, respectively.

Modified Kramer scale and transcutaneous bilirubin method was developed with the intention of having a test which is simple, reliable, accurate and to avoid repeated blood sampling. STrIP score has all the benefits as above along with added advantage of promising predictive accuracy.

Authors conclude-"STrIP score has the best agreement with serum bilirubin in neonates compared to other non-invasive techniques such as transcutaneous bilirubinometry and clinical assessment using Kramer scale."
