Performance of Bilirubin Determinations in US Laboratories—Revisited

Abstract
Background: The diagnosis and management of hyperbilirubinemia in the newborn requires accurate and precise bilirubin determinations. We evaluated the current status of bilirubin measurements in US laboratories by examining data submitted by laboratories participating in the College of American Pathologists (CAP) Neonatal Bilirubin (NB) and Chemistry (C) Surveys.
