<p>There isn’t a blood test or a genetic test, no, but a lot more than a conversation with a doctor happens when someone is legitimately screened for ADHD. There are numerous tests that are performed and the patient undergoes hours of scrutiny of their behaviors and abilities, complete with interviews with parents and, at least in my day, with teachers. I suppose if you think there’s no way to test for ADHD, there’s no way to test for dyslexia or aspergers either, right?</p>
