Differential Diagnosis

Clinical history in the presence of laboratory prolongation of PT and PTT usually suggests FX deficiency. Specific diagnosis relies on the quantification of FX activity and antigen levels and on the levels of other coagulation factors. Concomitant disease may mimic congenital FX deficiency. Liver disease and vitamin K deficiency can be responsible for acquired FX deficiency, but they more commonly determine abnormalities of other VKD clotting factors. Acquired FX inhibitors have been reported and can be suspected when sample plasma added to normal plasma causes prolongation of PT and PTT. Amyloidosis has been shown to determine FX deficiency by amyloid protein binding to circulating FX.
