Diagnosis
If your child has a history of bleeding—especially joint bleeding—or excessive
bruising, your doctor may suspect a bleeding disorder. Simple blood tests are
the standard for diagnosing a child with hemophilia. The tests will check the
level of factor VIII and factor IX in the child’s blood. If the tests show an
insufficient amount of factor VIII, the diagnosis will be hemophilia A, the
most common type of hemophilia. An insufficient amount of factor IX means a
diagnosis of hemophilia B. Depending on how low the levels of factor VIII or
factor IX, the child’s hemophilia will be classified as mild, moderate, or
severe.
