<prompt> Answer this question truthfullyWhat are the laboratory results associated with hemophilia?  <response>: <reason> The diagnosis of Hemophilia A and B may be suspected as coagulation testing reveals an increased PTT in the context of a normal PT and bleeding time. The diagnosis is made in the presence of very low 10 IU levels of factor VIII IX. A very small minority of patients has antibodies against factor VIII that impair its functioning. Management of these patients is more complicated. Development of these inhibitor antibodies in Hemophilia B patients is even much less common; but when present, they make the treatment process of the disease very difficult .
