[[Coagulation Factor Deficiency|Deficiencies]] in clotting factors are often the result of congenital deficiency in one or more of the coagulation factors and can lead to ineffective blood clotting and development of a disease syndrome characterized by excessive bleeding - deficiencies are often detected following trauma or surgery. Occasionally bleeding may be spontaneous (e.g. into alimentary or urinary tracts). Deficiencies are often seen as familial inherited problems; Haemophilia (factor VIII deficiency) is probably the best understood condition.
