Cautions

Venous blood collected in heparinized vacuum tubes with gel separators (all volumes) and non-gel
vacuum tubes (2 mL only) are not suitable to measure COHb. This is a result of gamma irradiation of vacuumtube material during sterilization which generates carbon monoxide in the tube head space resulting in nonphysiologic COHb elevation.
