I haven't been tested yet, but my knowledge of AS is such that I consider myself self-diagnosed. My aspie quiz score was 171/200. I was gob-smacked.
I think it is actually a very well constructed test, and has a full diagnostic report with it as well, showing all your answers and how they relate/or not to AS.
