Activation of plasmin and inhibition of thromboplastin production make the dynamic balance between fibrinogen and fibrin and prevent the production of fibrin filament; At the same time, because they are involved in the metabolism of cellular enzymes and ions, the dosage of heparin will affect the detection value.
