Hrm.

There is no real information at all about the proposed blood test- what precisely it is screening for or anything. I'm really... Um, challenged to come up with how that might work. But I'm not a full-fledged member and spokesperson of Autism Speaks, so what do I know...

Also, I couldn't find any references for the article and nothing published by this guy [Eric Courchesne] about blood tests and autism.

It's possible I didn't dig deep enough or in the right places but... I still call shenanigans on this...
