title: Prediction of later hyperbilirubinaemia by measurement of skin colour on the first postnatal day and from cord blood bilirubin.
abstract: The study comprised 138 mature and healthy newborns admitted to the newborn nursery. The performance of cord bilirubin, yellow skin colour on the first postnatal day, and the increase in skin colour during the first postnatal day was evaluated as a test for later hyperbilirubinaemia, defined as a serum bilirubin concentration above 200 mumol/l on the third postnatal day. All three tests performed well as tests for later hyperbilirubinaemia and had closely similar receiver operating characteristic curves. Combination of the three tests by the technique of logistic regression showed an even better test performance, and it was found that each single parameter contributed significantly to the prediction.
