Types of additives
Anticoagulant
Clot activator
Thixotropic gel
What do additives do?
- Inhibit-stopping the process coagulation
- Initiate-starting the process of coagulation
- Separating blood layers
Purpose of anticoagulant?
Inhibit the blood clotting process, letting the blood collected in the blood collection tube stay in the liquid form
