vital wheat gluten for gluten challenge?

TLDR; how much vital wheat gluten flour is equivalent to 10g gluten daily, for a gluten challenge?

------------------------------------------------------

Hi all. A recent blood test has revealed that I am low in iron (ferritin 17 mcg/L for 29 yo female with no heavy menstrual flow). I can't remember if I have always been low, but it doesn't surprise me. However, I am not anaemic. I don't believe that I exhibit any other signs for celiac however I know that that doesn't mean that I am negative. My diet is reasonably rich in iron, I eat meat almost with every meal.

My doctor would like me to get tested for celiac and warned me to eat gluten (2 slices of bread + small serve of pasta) for 6 weeks prior to the test. I haven't had a 'gluten free' diet per se, but upon a review of my diet, I realise that I do 'coincidentally' have a low gluten diet. Thus to ensure that my test results are as accurate as possible, I want to undergo a gluten challenge before doing my blood test... and in the lowest carb option possible.

I've done a lot of research over the last 2 days (scientist by trade) and I can see that an 'acceptable' gluten challenge is 3-4 slices of bread (approx. 10g gluten) for 4-6 weeks. I can see that vital wheat gluten flour has been used by some for their gluten challenge but I cannot for the life of me find how much vital wheat gluten flour to ingest for a meaningful gluten challenge. Initially I thought that it would be 10g flour but I'm not so sure...

Can anyone confirm or share their experiences? Thanks in advance!!

We normally suggest minimum gluten consumption for many that have symptoms to make it bearable, and they get by with 1/2 slice of bread a day or 1tsp vital wheat a day. If you want to push it like your doing maybe 2-4 tsp taken in 2 doses?
I swear I should have done a binge fest before mine but I had gotten to the point of thinking I was dying with the neurological symptoms and pain. I was already gluten free and we just went with obvious reactions to gluten in the office.....and endoscope which still had damage back then.

Thank you! I don’t really get symptoms so it’s hard to say, I might start with 1/2tsp and build up to 4tsp by week 2 as you have suggested. Thanks again!
