Specimen Collection Procedure: (Call lab for special tubes) 1. Draw three tubes gray, red, purple per patient. Important: Gray tube first, then the other two in no particular order. 2. The tubes are vacuumed to only accept 1 mL. Tubes fill slowly so keep tube on the needle for 2-3 seconds after tube appears to have completed filling. 3. When tubes are filled shake GENTLY AND MAKE SURE THE INSIDE OF THE TUBE IS COATED WITH BLOOD for 10-12 seconds. The shaking is extremely important as there are reagents in the tube. 4.
