Specimen Collection & Preparation

Specimen Requirements:

-OR-

0.5 mL Whole Blood in a 3.0 mL Syringe with Heparin
Minimum Volume:
0.5 mL Whole Blood*

* This volume does not allow for repeat testing

Collection Instructions:

Venous specimen

All extra air must be expelled at collection from syringe

Remove needle from syringe before submitting to the laboratory


Rejection Criteria:

Whole Blood in a Green Top Tube - Li Heparin


-OR-

0.2 mL Whole Blood in a Tuberculin Syringe with Heparin
Minimum Volume:
0.2 mL Whole Blood*

* This volume does not allow for repeat testing

Collection Instructions:

Venous specimen

All extra air must be expelled at collection from syringe

Remove needle from syringe before submitting to the laboratory


Rejection Criteria:

Whole Blood in a Green Top Tube - Li Heparin


Clinical Interpretation

Reference Range:

Non-smokers and light smokers (1-2 packs a day): 0.5% - 5.0%


Critical Ranges:

 > 10%


Test Comments:

Due to the tube manufacturing process, falsely elevated CO values may be seen when a lithium heparinized (Dark Green) vacutainer tube is utilized. Because of this a vacutainer is an unacceptable specimen for CO testing.

CO testing alone does not require the use of ice for specimen transport, but the value will be unaffected by iced transport of the specimen, if needed for other shared blood gas testing.
