Whilst it's not the only cause, imbalances in blood serotonin levels are evident in autistic individuals. It's probably due to secondary conditions, but it's still there. Not to say the doctor is correct, but without more information from the OP, one could say the doctor meant that chemical imbalances are found in those with autism. "'...chemical imbalance or probably a chemical imbalance or something.'" Doesn't sound too revealing of the doctor's intentions.

Just because one thinks they have something that's defined by the professional majority due to taking an online test, reading a personal and subjective account, doesn't mean they have it. I can bend myself to fit almost any mental disorder in my subjective opinion of my own actions and thoughts; I can give persuade myself that I have schizophrenia, it doesn't mean I objectively have it. I'd trust the opinion of a professional than not, even if there's a chance that the professional is wrong due to inexperience; more times than not they aren't. One can always get a second opinion; a third, fifth and tenth if they so wish.
Ironically, these disorders are defined by the professionals, i.e., those who give out the official labels. Using the same logic above, there's no point in saying one has one of these conditions as the professionals who defined them were possibly wrong in their observations [of the disorders they just defined].
