#466 - [Journal Club] - 📌 Do We Still Need a DAT on Every Newborn at Risk of Hemolytic Disease?

Send us Fan MailDo we really need a DAT on every baby born to a group O or Rh-negative mother? This week on Journal Club, Ben and Daphna dig into a new Pediatrics study questioning routine Direct Antiglobulin Testing (DAT) in low-risk neonates with ABO or RhD incompatibility. Using data from over 1,300 infants, the authors found that transcutaneous bilirubin alone predicted the need for phototherapy just as well as DAT in ABO-incompatible babies, and that passive anti-D from RhoGAM rarely caused significant hemolysis in RhD-incompatible infants. Ben and Daphna also discuss what this means for institutions running DAT on every newborn, how to tell passive anti-D apart from true alloimmunization, and why a more targeted approach to bilirubin screening may be overdue.----Utility of DAT in Low-Risk Neonates With ABO or RhD Incompatibility.
