2. Posted LA Patients with factor XI deficiency have normal prothrombin times. Therefore, their international normalized ratio is normal. All patients with a hemophilia factor deficiency, no matter what the phenotype, have a prolonged partial thromboplastin time (PTT).

2011-08-16 · Factor XIII deficiency is an extremely rare inherited blood disorder characterized by abnormal blood clotting that may result in abnormal bleeding. Signs and symptoms occur as the result of a deficiency in the blood clotting factor 13, which is responsible for stabilizing the formation of a blood clot.

In Iran, a Middle Eastern country with a high rate of require further tests. For a prolonged PT and aPTT above the reference range, it is especially important to consider if and what kind of bleeding symptoms are observed.4 Mixing Studies: Distinguishing factor deficiency from inhibitors A mixing study is used to further investigate the cause of a prolonged PT and aPTT.
