3 mL arterial blood in heparinised sealed syringe immersed in crushed ice.
Precaution:Ensure that there is no air space in the syringe and air bubbles present in the syringe are expelled. Tightly seal the syringe nozzle to avoid exposing collected blood to air. The syringe should be gently rotated between the palms of the hands to ensure good mix of blood and heparin. The specimen should then be clearly labelled, placed in a biohazard bag and immersed in another bag with crushed ice and despatched immediately to the laboratory.
Keep cold with ice and send immediately to the laboratory.
