A diagnostic assessment provides information related to your child’s diagnosis and is completed by a licensed physician or psychologist. AB Spectrum has a licensed physician with experience diagnosing Autism Spectrum Disorder (ASD) as part of our team of providers.

If your child’s pediatrician has indicated that your child is at risk of a diagnosis of autism, but didn’t provide the actual diagnosis, we can help.  There is no need to sit on a wait list for 9 to 12 months to see a developmental pediatrician.

Our first step will be for you to complete an M-CHAT (Modified Checklist for Autism in Toddlers), especially if your child is young (18 months – 3 years).  We have this assessment available for you to complete below or at the M-CHAT website 

If the M-CHAT screening indicates a risk of ASD, we will invite you to our office for a more formal diagnostic assessment called ADOS-2 (Autism Diagnostic Observation Schedule, 2nd edition).  This is the primary test that is used to make a formal diagnosis of ASD, and we can administer this test. We’ll also request records from your child’s pediatrician or other healthcare providers.  Then, our physician will review the records and make a formal diagnosis.

A formal diagnosis is required by an insurance company before they will pre-authorize any ABA therapy benefits relating to Autism Spectrum Disorder.  Our goal at AB Spectrum is to simplify the access to care for our clients – that’s why we offer assessments, diagnosis, as well as help communicating with the insurance company on your behalf.
