Neonatal screening of ABO/RhD blood group and direct antiglobulin Coombs test. Experience of a single institution.

Background: Evaluating the ABO/RhD blood group and the direct antiglobulin Coombs test (DAT) at birth is recommended good practice, but there is variability in its universal implementation. This study aims to show the comparative results in various variables of clinical impact during the hospital stay of neonates with positive DAT compared with those with negative DAT, based on the systematic detection of the ABO/RhD group and DAT at birth.

Methods: Newborns between 2017 and 2020 in a high-risk pregnancy care hospital were included.
