When parents are advised that they should have their child “tested” for Asperger’s Disorder what they really are being told is they should have their child evaluated. Testing refers to specific laboratory exams that give exact answers to whether or not something exists, such as a bladder infection or a broken bone. No medical test currently exits that can determine if someone has Asperger’s Disorder. There are some medical tests, however, that your child’s pediatrician or neurologist may recommend in order to rule out physical causes of your child’s symptoms.
There are also no psychological or educational tests that will definitively determine if a child has Asperger’s Disorder. However, there are several checklists and tests specifically designed to aid in the evaluation of Asperger’s Disorder. You and your child’s teacher may be asked to complete one or more questionnaires as part of the evaluation process. In addition to a detailed history, observation of your child, a review of his records, and a behavioral analysis, psychological and educational testing can be helpful as part of the diagnostic evaluation.
