A Factor VIII (FVIII) (or antihemophilic Factor A) deficiency or dysfunction leads to hemophilia A, which is an hereditary or congenital hemorrhagic disease.
Elevated concentrations of FVIII are observed in inflammatory or hepatic diseases and may be suggestive of an increased risk of venous thrombosis.
The FVIII concentration is increased during pregnancy.

A Factor IX (FIX) (or antihemophilic Factor B) deficiency or dysfunction leads to the hemophilia B disease, an hereditary or congenital coagulation disorder. FIX levels are reduced in patients receiving anti-vitamin K treatment, or in diseases such as liver disorders, cirrhosis or DIC. High FIX concentrations may be suggestive of an increased risk of venous thrombosis.

Willebrand's disease is the most common bleeding disorder. It concerns a group of various types of von Willebrand disease. vWF functional or quantitative deficiency allows characterizing von Willebrand disease, which can be classed into 3 types:
   • Type 1: vWD is characterized by a partial quantitative deficit of vWF (most frequently).
   • Type 2: vWD is characterized by an abnormal vWF adhesion activity. It is divided into 4 subtypes: 2A, 2B, 2M and 2N, depending on the multimers functional abnormality.
   •Type 3: vWD is characterized by a severe quantitative vWF deficiency.

vWF deficiencies can be associated with various other pathologies, thus constituting an acquired von Willebrand disease. When vascular endothelium is affected, the vWF concentration can be increased in relation to inflammatory processes.
