The PT (prothrombin time) result falls within the normal range and the INR (international normalized ratio) is within the therapeutic range for a patient on warfarin. APTT (activated partial thromboplastin time) is prolonged, indicating a possible deficiency in the intrinsic pathway. BT (bleeding time) is prolonged, which can also indicate a platelet disorder. The decreased aggregation in ristocetin test suggests that it is related to von Willebrand's disease. Therefore, the patient is most likely suffering from von Willebrand's disease.
