I never said there weren't tests. I said diagnosing ASD, like most mental and/or developmental disorders, can't be done on the basis of a single definitive tests or a group of tests alone. And I said as the CDC does, an evaluation for ASD doesn't have to include any traditional tests. I still say those things. Even the blurb for a commercially available observational device (ADOS-2) provided by another poster cautions it should be part of a "comprehensive evaluation" and cannot be used alone to make a diagnosis.There are tests for autism conducted by Psychiatrists assisted by Psychologists with specialist training. It's a discrete tests and isn't covering other issues such as co-morbid personality disorders or PTSD or addiction etc.
Clinical psychologists, psychologists trained to work with people with mental illness, actually receive more training than psychiatrists do re: doing mental health diagnosis. Psychiatry these days is very focused on using drugs for treatment. In many cases when a treatment team approach, is used, the doctoral-level psychologist does the diagnosing while the psychiatrist does the prescribing.
I would agree it's possible for an evaluation to focus only on ASD. At issue would be the referral question. Usually there are troubling symptoms and the goal is to determine why and if they are part of a known disorder. In that case, the referral question is fairly broad and looks at many possibilities. If BK was evaluated as a child, IMO the evaluation was probably broad but none of us can know for sure. But it doesn't have to be done that way.
