Which quiz did you do? Eg. AQ, RDOS(This one is for entertainment), RAADS-R, etc...

Quizzes or questionnaires are used to screen, not diagnose. They are also good for getting a history, and identifying behaviours/thinking, that may or may not be causing difficulty.

Early childhood development has to be included in the assessment. Autistic traits are usually evident in the first few years of life.

A psychiatrist, psychologist and neuropsychologist can make an Asperger diagnosis. Some people don't bother and diagnose themselves based on internet quizzes.
