If you give the test to everyone, your results are:

~4.9% incorrectly diagnosed with autism (0.05 x .983)

~1.5% correctly diagnosed with autism (0.88 x 0.017)

Thus, 76% of those diagnosed would be diagnosed incorrectly.

That's true in a statistical sense. Or it's possible that the human-observers are less accurate about autism than this brain scan.

It's unclear if those who have the odd brain structure but aren't diagnosed are entirely asymptomatic.

Also they may be non-autistic in spite of this brain pattern, but nonetheless have a genetic predisposition to pass it on. Big step.

It's not a genetic test, and it isn't a test for something that defines autism, so you're begging the question IMO. Sure, human observers are imperfect, but that doesn't mean you can choose an arbitrary test that is precise and make it the standard just because.
