This report helps pediatric primary care providers quickly identify infants with biliary atresia, which has the potential to improve outcomes and reduce need for liver transplant. The strategy is intended to be used between 2 and 4 weeks of life at the "By 1 month" well-child visit in the Bright Futures/American Academy of Pediatrics "Recommendations for Preventive Pediatric Health Care." The strategy involves examining every infant's eye color, stool color, and prior laboratory results to determine whether measurement of a direct or conjugated bilirubin level is warranted.
