PAX!
You can get an Asperger diagnosis (well, maybe not in the USA) or an Autism diagnosis but I've never even heard of a Neurotypical diagnosis.

An example (that will never happen):
John has been meeting with psychiatrists and psychologist for some time and now they will give their final statement/report about his diagnosis. So they tell him that they think he's a bit odd and will diagnose him with NT....
This will obviously never happen!

If there can be AS and Autism diagnoses why not also have an NT diagnosis?
