There is no way to diagnose Autism
biologically, at this time. Researchers and doctors got
together at the first DAN! (Defeat Autism Now) Conference to
begin writing a manual called the DAN! Protocol. It lists
biological tests that may be helpful for autistic people.
It is available from the Autism Research Institute (ARI) http://www.autism.com/ari/main
For now, few doctors and other "experts" have
knowledge of the DAN! Protocol and instead evaluate
autism using psychological testing,
parent interview and observation of the child as well as the
parent(s) with the child.
