We got back DS's Sunderland urine test results today and they came back positive!
I feel a bit sad but also really happy to know that the gluten thing wasn't all in my head. Also so pleased we stopped it when we did.
We didn't actually go staight to the ARU at SU. We had it done through Breakspear Hospital (private hosp. in Herts that we'd booked for his single measles jab) However, they still called it the Sunderland test and sent the sample off to SU. I think the results measured peptides? Or something like that. We're going in next week for a consultation to explain where to go from here.
He indicated that we may only need to stay off the gluten til DS is 2.5 and his gut matures a little but we don't know yet.
Anyway, point of the thread is to say a huge thank you firstly to you Baka for your empathy over the gluten 'highs' and your info about the Sunderland test and to you, Ruty for your experience of the test and of your DS's gut problems. This helped me tie things together.
Oh and apparently we don't have a problem with milk as this was also tested. Not sure if this is unusual to be intolerant of just the gluten but it's good to know as he loves milk and yoghurt.
Thank you both again.
P.S Why isn't this info available from G.Ps?
