Fibrin is formed through polymerization and is the component of the clot, that stops the bleeding.The doctor may recommend the fibrin test if the patient shows deficiencies in coagulation or if suffering from massive bleeding. The normal values of fibrin in the blood: 200-400 mg per 100 ml of blood.ibrin is formed through polymerization and is the component of the clot, that stops the bleeding.

Blood Clots: Plugging the Breaks. When an injury causes a blood vessel wall to break, platelets are activated. They change shape from round to spiny, stick to the broken vessel wall and each other, and begin to plug the break. They also interact with other blood proteins to form fibrin. Fibrin strands form a net that entraps more platelets and blood cells, producing a clot that plugs the break. Formation of a clot also involves activation of a sequence of blood clotting factors that generate thrombin.
