Diagnosing autism can be difficult because there isn't a medical test that can be done to diagnose the disorder. For example, doctors can't take blood tests to diagnose them. Doctors look at the child's behavior and development to determine whether or not the child has autism.

​

There are two steps involved in diagnosing ASD. The first is developmental screening. This is a short test to see if the child is learning basic skills when they should, or if they might have delays. During this step, the doctor might ask the parent a few questions or talk and play with the child to see how he/she learns, speaks, behaves, and moves. If a delay in any of these areas is noticed, there could be a problem.

 

The second step involved in diagnosing a child with ASD is a comprehensive evaluation. This is a thorough review that includes looking at the child’s behavior and development and interviewing the parents. It could also include a hearing and vision screening, genetic testing, neurological testing, and other medical testing. Sometimes, the doctor may choose to refer the child and the family to a specialist for further assessment and diagnosis.
