Hi,
Yes, there is a lab at the University of Sunderland which investigates the impact of diet on autism. They will do urine samples for a relatively modest fee, but I'm not sure how useful the results are, as they are not conclusive.
We decided not to go that route, but just tried modifying diet to see if it had an impact. If you remove casein (dairy) products from your child's diet, you will usually see some results within a month. The effects of gluten removal can take much longer - some say up to a year.
In my son's case, we saw no impact from removing dairy, but he told us 6 months later that the stomach pains had ceased after dairy removal (what stomach pains?!). We also saw significant improvement in his alertness after one week off gluten, and a general improvement in diet after that.
I would recommend giving it a try. There are some good books on the market to help you get started, such as "The Kid-friendly Autism and ADHD diet book".
Good luck with whatever you decide.
