Overview
Laboratory Findings
The diagnosis 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. A very small minority of patients has antibodies against factor VIII that impair its functioning. Management of these patients is more complicated.
- Prolonged partial thromboplastin time (PTT)
- Normal prothrombin time
- Normal bleeding time
- Normal fibrinogen level
- Low factor IX
