Hemophilia A Diagnosis

If you think you or your child may have a bleeding disorder, see a healthcare professional for a diagnosis. This will help ensure that you receive appropriate treatment and learn the necessary steps to take when a bleeding episode occurs.

What to expect

During your visit, your healthcare professional will likely first ask about the hemophilia symptoms you or your child have been experiencing, as well as your personal and family medical history.

Your healthcare professional will also perform a physical exam and order blood tests. These tests are very important in diagnosing the condition, as they can help healthcare professionals determine:

  • How long it takes your (or your child’s) blood to clot
  • The levels of clotting factors in the blood
  • The type of severity of the condition
