What Is Involved in Making a Diagnosis of Hemophilia?

The experimental diagnosis of hemophilia is the diagnosis of hemophilia through laboratory tests. Laboratory tests include routine blood tests, coagulation screening, coagulation factor activity and antigen determination, and genetics. Hemophilia is a group of hereditary bleeding disorders caused by hereditary coagulopathy, including hemophilia A, hemophilia B, and factor XI deficiency. Hemophilia A is more common.
