This is literally exactly what I need. I'm doing a gluten challenge right now, but my doctors are honestly idiots. One made me go to the first blood test while I explicitly asked her whether I need to be on a gluten-containing diet for the test to work.
And she said "no, it's fine to go even when you have been eating gluten".
So idk, she was calling me from 5 years in the future or she made a mistake. Now I asked for them to redo it, and specified myself it needs the gluten challenge, this doctor said "a week should be enough". When I look it up, the recommendation is around 8-12 weeks.
So yes pls, can I get one of those proper new tests so even the idiot doctors in Finnish public healthcare can manage something?
