Yes, it's possible. Go into the General Autism forum here at WP! There is at least one post article with links to online tests. Take the tests to give you some idea of where you stand. Save the results, and print out at least two copies, one for your records, and one to show a psych doc. If you want an official check on where you stand take one of the copies with you to a psych doc experienced in treating adults on the Autism spectrum, and tell the doc about your doubts.
