Ok thanks for the links, you've convinced me! Pasta for lunch today then.

I was actually gluten-free a couple of weeks before the bloods, I told my doc this and he didn't seem too worried, so maybe thats why the other tests were negative. Been gluten-free around 5-6 weeks now.

Not sure when the biopsy is, am waiting for the letter, where i come from these things normally take a while so prob get my 4 weeks of gluten in before then. I am really keen to sort out my brain fog asap (writing my thesis at mo and am a long way behind schedual), so that's why i was reluctant to do anything that might set my progress back a couple of months.
