title: Validity of arterial hematocrits in newborns.
abstract: Various methods are used to obtain specimens for hematocrit determination in neonates. We evaluated arterial sampling and found this method to be acceptable. Arterial values correlated closely with simultaneously obtained venous samples. Venous blood obtained with a tourniquet had a significantly higher hematocrit than that obtained without a tourniquet.
