Autism Spectrum Disorder Diagnostic Hub

The Autism Spectrum Disorders (ASD) Diagnostic Hub provide a multi-disciplinary diagnostic evaluation of children and youth suspected to have autism spectrum disorder. As part of our assessment, we focus on the child and youth’s functioning and challenges across different settings, such as home and school.

For more information, visit the Autism Spectrum Disorder Diagnostic Hub page for patients and families.

Patients/Conditions To Refer

Children and youth referred to the ASD Diagnostic Hub should have a query of autism based on history, observations or screening in the community. If a diagnosis has already been made, you may refer the child or youth to our general developmental clinic with your specific question for referral.
