Factor II deficiency

Hypoprothrombinemia; Factor II deficiency; Dysprothrombinemia

Prothrombin deficiency is a disorder caused by a lack of a protein in the blood called prothrombin. It leads to problems with blood clotting (coagulation). Prothrombin is also known as factor II (factor two).

Blood clot formation

Blood clotting normally occurs when there is damage to a blood vessel. Platelets immediately begin to adhere to the cut edges of the vessel and release chemicals to attract even more platelets. A platelet plug is formed, and the external bleeding stops. Next, small molecules, called clotting factors, cause strands of blood-borne materials, called fibrin, to stick together and seal the inside of the wound. Eventually, the cut blood vessel heals and the blood clot dissolves after a few days.

Blood clots

Blood clots (fibrin clots) are the clumps that result when blood coagulates.
