Why Is This Case Important?

It is important for parents to understand there is no specific lab test or procedure to diagnose ASD.

Rather, the diagnosis is made on the basis of detailed information obtained from the child’s caregivers, careful observation of the child, and the use of standardized tools specifically designed to help diagnose ASD.The diagnosis may be made by a clinician who has expertise in the diagnosis of ASD or by a team of specialists that may include developmental-behavioral pediatricians, child neurologists, child psychiatrists, psychologists, speech-language pathologists, occupational or physical therapists, educators, and social workers.
