Confirming the Diagnosis

Hearing that your child may have Duchenne can leave you with more questions than answers. Confirmation is not about doubting what you were told. It is about making sure the diagnosis is supported by the right testing, that you have a copy of the results, and that you know what still needs to happen.

You don't have to interpret the results alone.

What does "confirmed" mean?

A diagnosis may begin with symptoms, a physical examination, family history, or a very high creatine kinase (CK) level. Those findings can make Duchenne highly likely, but genetic testing is what usually identifies the specific change in the DMD gene and confirms the molecular diagnosis.

  1. Suspected

    The child's symptoms, examination, development, family history, or bloodwork suggest Duchenne.

  2. Clinically diagnosed

    The medical team believes the pattern is consistent with Duchenne, even if the full genetic result is not yet available.

  3. Genetically confirmed

    Testing has identified a disease-causing change in the DMD gene that fits the diagnosis.

Different clinicians may use these terms somewhat differently. Ask your care team exactly what has been confirmed and what is still pending.

What tests help confirm the diagnosis?

Several types of information may be used to confirm Duchenne.

  • Clinical history & examination
  • Creatine kinase (CK) blood test
  • Genetic testing
  • Other testing when needed

What if something doesn't match?

An unclear result doesn't always end the diagnostic process.

  • Negative or unclear results can happen
  • Additional testing may be needed
  • Specialist review can help clarify
  • Don't try to interpret it alone

Questions to Ask Your Care Team

  • Has the diagnosis been genetically confirmed?
  • What exact DMD gene change was found?
  • Was the result classified as pathogenic?
  • Did the testing include deletions & sequencing?
  • Is any additional testing recommended?
  • Should we meet with a genetic counselor?
  • Should family members be tested?
  • Can you send us the complete report?

What We Wish
Someone Had Told Us

It's okay to ask the doctor to slow down and explain what has actually been confirmed.

Ask for every report. Keep your own copies. Write down what is still pending. You may need those records many times, and no parent should have to rely on memory from the hardest appointment of their life.

An unclear answer doesn't mean you did something wrong, and asking for another review doesn't mean you are being difficult. It means you are making sure your child's care begins with the clearest information possible.

You are allowed to ask, "How do we know?"
