Specimen Requirements

Indicate whether specimen source is arterial, venous, or capillary.

Fill blood gas syringe or capillary tube to the recommended capacity or use the least amount of liquid heparin anticoagulant that will prevent clotting. Mix blood and anticoagulant by rolling syringe between palms for at least 5 seconds and then inverting the syringe to maintain anaerobic conditions. Forward STAT at ambient temperature.
