asperger's is a clinical diagnosis. there is no lab test to diagnose it. there are imperfect rating scales that can be used to guide the clinician but in the end the diagnosis needs to be made by a professional with considerable experience in this area. you may be best off going to see a developmental pediatrician or child psychiatrist with demonstrated (or declared) interest in "autism spectrum disorders which includes asperger's. social awkwardness and difficulties with subtleties of language are other common features of asperger's. your pediatrician may be able to suggest a different consultant to evaluate your child. to have a child evaluated for suspected asperger syndrome you should seek out a physician or psychologist who specializes in the evaluation of children with autism. among physicians a developmental pediatrician may be your best bet but a child neurologist or child psychiatrist with a defined interest in autism spectrum disorders are other options. you can also go to an autism center -- ideally at a children's hospital or major medical center.
