title: Sodium fluoride in delayed measurement of umbilical blood gases.
abstract: In blood samples stored at 5 degrees C with 20 mM sodium fluoride, only small changes in blood gas measurements were observed over 24 h. Most of the changes occurred within the first 2 h after collection. In samples stored at 5 degrees C without fluoride, blood gas measurements showed continuous changes over the 24-h period.
