Many causes: Ptt is a screening test that tests for the status of multiple coagulation factors in blood. There are a variety of reasons for prolonged PTT results. Typically, the possibilities are addressed by hematologists and can be due to factor deficiencies (acquired or genetic) or to inhibitors. Some factor deficiencies (xi, ix, viii) identified by PTT prolongation cause bleeding. Some (xii) do not.

PTT: An elevated PTT can be an imdication that you are at risk of bleeding easily or something is interfering with your coagulation factors. That is why you need a hematologist, for evalution of why your PTT is high
