Put on clean disposable gloves. Prepare 10cc syringe with heparin flush.
Screw vacutainer needless connector on vacuum collection system holder, and attach blunt cannula.
Wipe injection cap with alcohol swab. Take the cap off the blunt cannula and poke into the injection cap. Put the 3cc red top tube into the vacuum collection system holder. The pressure in the tube will allow 3cc of blood to go into the tube. This blood is your waste.
