Post oxygenator ABG
Sample Requirements
Specimen: Whole Blood
Container(s): Heparinized Syringe
Preferred Vol: 1.0 mL
Minimum Vol: 0.8 mL
Note: Avoid air bubbles. Expel air from syringe and cap it immediately after obtaining the sample. Send to the lab immediately. Ideally, whole blood specimens should be analyzed within 15 minutes of blood draw. Place specimen in OUTSIDE pocket of a pre-filled biohazard bag of ice, then put into a separate biohazard bag for transport.
Processing Instructions
