Cord blood sampling for neonatal admission laboratory testing-An evidence-based blood conservation strategy.

Historically, blood for admission laboratory studies in neonates was obtained through direct neonatal phlebotomy. Over the past decade there has been an increase in studies evaluating the validity and clinical impact of using a cord blood sample for many admission laboratory studies. This article reviews various studies that together have shown that using cord blood samples for admission testing in neonates is both acceptable and beneficial.
