Autism testing

Pretty soon my little prince will be tested for Autism.  I've looked up the red flags online, and I've read about the "quirks" and such and figure this is a good idea and wonder why they haven't brought it up before.  What I'm afraid of is the label.  Once labeled, you're labeled for life.  He won't be able to shake it.  And I'm afraid of being one of those parents who dismisses everything, saying "oh, nobody understands him, it's the autism." "let him get away with that, he has autism." "He does that because of his autism." I hate that.  I don't want to dismiss his behaviour, I want to let him know that some of his behaviours are inappropriate and should stop.  I don't want to enable the inappropriate behaviours. I guess I'll wait and see what the school psychologist, social worker, and such say about it.  They'll be calling me for a home visit soon.
