Coagolation tube

Vacuum blood collection system is known as the safest method to draw blood directly. FAR TEST coagulation tubes are used in various kinds of blood coagulation tests include evaluating Prothrombin Time, Activated Partial Thromboplastin Time, Thrombin Time and etc. Tri-sodium citrate solution chelate (bind) calcium ions of blood cause to prevent the blood clotting. Their concentrations are 0.129mol/l (3.8%) or 0.109mol/l (3.2%) depend on laboratory manuals.
