The coagulation screen is showing a prolonged bleeding time but the PT and APTT are both within normal limits. This is consistent with von Willebrand Disease type 1, which is a deficiency of von Willebrand Factor. Hemophilia A and B both show prolonged APTT, while factor X deficiency shows prolonged APTT and PT.
