My DD tested there - am surprised you got in so quickly as there is usually a ridiculously long wait - did you grab a cancelled one?
Dr Lewis is great and really knows how to put kids at ease.
Take water and snacks for sustenance during the test particularly if it spans lunch time. I didn't do this with my DD like a typical oblivious dad and I definitely saw my DD flag towards the end.
Also be sure that he will tell the tester if he needs 'to go' so he will not be distracted by things like an uncomfortably full bladder.
You will have the chance to view the test via a two-way mirror should you wish to or at least I could. Quite insightful.
