Inside the tube wall, where is well sprayed with lithium heparin or sodium heparin which is a kind of anticoagulant activating antithrombins to block the coagulation cascade reaction.

The anticoagulant is Heparin, which can block the coagulation cascade reaction. The obtained plasma specimen is used for emergency biochemistry test and blood rheology test after centrifugation.
