Hemophilia (cont.)

Exams and Tests

A family history of bleeding disorders aids in diagnosing hemophilia. But certain tests help quantify the disease.

  • Pronounced bruising at childbirth or bleeding with circumcision may suggest a case of severe hemophilia.
  • A moderate case of hemophilia may become apparent during the toddler years when falls are common.
  • A mild case may not become evident until adulthood when you need surgery.
  • Blood tests can be performed if you have any reason to suspect hemophilia.
    • Blood may be checked directly for certain factors.
    • Test results will be low depending on which form of hemophilia you have.
    • In either case, your activated partial thromboplastin time (aPTT), a measurement of the clotting of blood, will be prolonged.
