Looking for someone who has been through a recent diagnosis of coeliac disease with a child.

DD has just had a BT for coeliac disease. My mum has it and I'll be having the BT too when I have my GD test in a few weeks, but we did the BT for my DD when we were at the GP last week. No BT results yet, but if it does come back positive, what are the next steps?

I know what happened with mum - gastroscopy straight away for full diagnosis. Simple procedure for her, under twilight anaesthesia. What do they do for kids? Does a twilight anaesthetic work for kids?

Possibly counting my chickens before they hatch but I just want to be prepared.
