Hemophilia
Diagnosis of Hemophilia
Blood tests A doctor may suspect hemophilia in a child (especially a male) who bleeds without an apparent cause or bleeds more than expected after injury. A blood test can determine whether the person's clotting is abnormally slow. If it is, further blood tests to measure the levels of factor VIII and factor IX can confirm the diagnosis of hemophilia and can determine its type and severity. At some specialized centers, Genetic Screening Before Pregnancy is available for women who may be carriers of the abnormal gene and for prenatal testing of a fetus.
