No, but you have to call them to get it. It's generally a good idea to call Direct Labs and mention the autism treatment list when ordering any test. You often get a discount that way that is not available if you order online. However, last I checked there was no discount for the plasma sulfate and plasma cysteine kit. I think it's $135. W.
