DDAVP (Desmopressin) is commonly used in the treatment of persons with bleeding disorders such as hemophilia, von Willebrand disease, or qualitative platelet disorders to help them clot better. The investigator wants to assess the increase in the subjects' clotting factors in response to intravenous DDAVP (Desmopressin) and the levels of these internal clotting factors will be measured at different times after the medication is given. The investigator will compare the response to DDAVP (Desmopressin) in adult hemophilia A carriers to women with a diagnosis of qualitative platelet dysfunction.
The purpose of this study is to determine how female hemophilia A carriers respond to a medication called DDAVP (Desmopressin).
