The most common indications for phlebotomy after birth include care processes for any infant admitted to the neonatal intensive care unit, early-onset sepsis evaluations, and congenital anomalies. Postnatal umbilical cord blood sampling (PCBS), rather than obtaining blood from the neonate, decreases neonatal blood loss at a critical time of extrauterine transition and prevents phlebotomy pain in infants without a catheter for blood drawing. Studies of PCBS in very low birth weight infants suggest additional benefits including more stable blood pressure and decreased need for vasopressors and erythrocyte transfusions in the first week after birth.<\/jats:p>\n                  <jats:p>PCBS can be used for any full-term or preterm infant when the need for phlebotomy is known at or shortly after delivery. PCBS can be used for complete blood cell counts, blood cultures, blood typing and antibody testing, genetic testing, select chemistries, and coagulation studies. Additionally, PCBS allows the collection of larger blood volumes for blood culture, potentially improving pathogen detection. Finally, PCBS can be performed after delayed cord clamping or cord milking and in conjunction with research studies and\/or cord blood banking. This report describes the evidence, safety, and methods for collecting cord blood after delivery.<\/jats:p>","DOI":"10.1542\/peds.2025-071811","type":"journal-article","created":{"date-parts":[[2025,5,26]],"date-time":"2025-05-26T20:02:48Z","timestamp":1748289768000},"source":"Crossref","is-referenced-by-count":15,"title":["Postnatal
