title: Parental infant jaundice colour card design successfully validated by comparing it with total serum bilirubin.
abstract: OBJECTIVE
  We designed a jaundice colour card that could be used by the parents of neonates and validated it by comparing it with total serum bilirubin levels.
  
  
  METHODS
  There were 106 term Chinese neonates in the study. The majority weighed between 2500 g and 3499 g (63%) and had a gestational age of 37-40 weeks (77%). The jaundice colour card and photometric determination were used to screen for neonatal jaundice and compared with serum bilirubin.
  
  
  RESULTS
  The bilirubin levels were measured by mothers using the jaundice colour card, and 67% of the measurements were taken at 11-20 days (range 3-30). The measurements at the infant's forehead, cheek and sternum showed strong correlations with total serum bilirubin. The mean differences between the total serum bilirubin and the jaundice colour card measurements from the forehead, cheek and sternum were 1.9 mg/dL, 0.3 mg/dL and 1.5 mg/dL, respectively. When total serum bilirubin >13 mg/dL was used as the cut-off point, the areas under the receiver operating characteristics curves were 0.934 for the forehead, 0.985 for the cheek and 0.966 for the sternum.
  
  
  CONCLUSIONS
  We established the validity of the jaundice colour card as a parental measurement tool for jaundice in Chinese neonates, and the cheek was the best measurement site.
