The prognosis of a patient with factor II deficiency depends on the etiology and severity of his or her disease. Although acquired factor II deficiency may be eliminated if the underlying cause is treated, the congenital form of the disease is lifelong. Despite the fact that specific levels of factor II correlate poorly with severity of symptoms, patients with very low levels of functional factor II have a greater tendency to hemorrhage and thus face a greater risk of life-threatening complications.
