How is someone tested for autism spectrum disorder (ASD)?

There is no medical test, such as a blood test or brain scan, to diagnose autism. Instead, a developmental or general pediatrician, neurologist, psychologist, psychiatrist, or other specialist will look at a child’s behavior and development to determine the diagnosis.
