Slide 10

June 2009

Our study design called for us to enroll up to 200 infants who had a serum bilirubin level ordered by a physician because they suspected jaundice.  For these infants, we performed a transcutaneous bilirubin reading within 30 minutes of a laboratory draw for serum bilirubin.  We compared the BiliChek transcutaneous bilirubin value to serum bilirubin measured by two different methods--one that uses a classic diazo reaction and the Vitros method that measures conjugated and unconjugated bilirubin photometrically.  We recorded gestational age, postnatal age in hours, and mother’s ethnicity for every infant enrolled in the study.
