Suitability of Placental Blood Sample of Newborns for Pre-Transfusion Testing

Background: Placenta is usually discarded after delivery. Using placental blood samples for pre-transfusion testing reduces the amount of blood collected for initial laboratory tests from newborns and potentially reduces the risk of developing iatrogenic anemia. This study compares placental blood samples with heel stick samples from newborns. Aims: This study aims to show concordance between heel stick and placental blood sample pairs for pre-transfusion testing of newborns, and to validate tube and gel methodology for placental samples. Methods: Placental samples were collected for pre-transfusion testing at birth from 76 singleton …
