Gluten Challenge -Is 3 Weeks Enough?


Reffinej

Recommended Posts

Reffinej Newbie

As of Friday I am officially doing a gluten challenge. Doc said 2 slices of bread, or equivalent, daily for 3 weeks then do the blood test.
I don't want to get a false negative, if I do have celiac disease, but don't want to have gluten in my diet longer than necessary. Conflicting info out there!

If you have been eating a normal diet up until now, then you probably do not even need to do that.  Most people eat the equivalent of 1-2 slices of bread (in the form of noodles, muffins, crackers, gravy, breaded meats, baked desserts) per day.

 

If you have been gluten-free, it is better to eat gluten for 8-12 weeks, with 12 weeks being better.  Some tests, like the tTG IgA, tTG IgG, and EMA IgA will be slower to increase, and to decrease.  After going gluten-free, it can take some celiacs a good year for their tTG tests to get back to normal.  The DGP tests (deaminated gliadin peptides) will change a bit faster, but possibly not within 3 weeks... probably not.

 

If you were having the endoscopic biopsy done, 3 weeks would be about right.

 

Good luck!

Ok,thanks. So I've been as gluten free as I thought I needed to be for health (thyroid antibodies) for 18 months, but without being strict about cross contamination. I had bloods done a few months back and had a high DGP-IgA result hence this journey.

You are most likely a celiac then.  The DGP IgA is pretty specific to celiac disease; around 95% of people with a positive test have celiac disease.  The fact that you were eating gluten-light and made a positive result - that's pretty meaningful.   :(

 

I would try to drag your gluten challenge out to at LEAST 6 weeks if possible.  If you make it too short you run the risk of getting false negative results, and then the doctors might discount that positive test (a mistake 99% of the time).

 

This report has some good info on the tests: Open Original Shared Link

 

Enjoy a guiness and a donut for me... not together though.  ;)

I agree that you need to be consuming gluten longer to get accurate test results since you have been gluten free.   Four weeks is enough for just the endoscopy.  8 to 12 weeks for another blood panel (University of Chicago celiac website).  

 

My GI doc ran the complete panel.  I tested positive on just the DPG-iga test.  The others were negative.  Yet, my intestinal biopsies showed moderate to severe damage (Marsh Stage IIIB).  My result was weird per my doctors.  But I am glad the entire panel was ran!  

 

Seems like you have celiac disease!  Plus, you have Hashi's like me!  

 

Welcome to the club!

Haha. not sure it's a club I want to be in! Oh well. 
I thought the DGP-IgA was pretty specific, my GP thought not (I like him so was disappointed we didn't seem to agree)....anyway, I guess I can just eat it for longer and do the test when I'm ready. But I am already feeling a bit dodgy from all the gluten. Although, I have to admit that I've enjoyed a couple of croissants- they're pretty much the one thing I miss. (Well, marmite on real bread is nice too)

Figure 2 in this paper shows the time course for antibody level increases during a gluten challenge. They didn't test at 3 weeks, but the values went up nicely sometime between 3 and 4 weeks. This was a small study, only about 20 patients, but this is a paper that people refer to for determining the length of a gluten challenge.

After my DPG-iga came back positive, I knew in my heart that I had celiac disease.  I had seven weeks in between my blood test results and endoscopy (work contraints), so I loaded up on even more gluten (I was eating gluten prior to my blood tests).  I ate a loaf of sourdough a day, I kid you not!  Plus, I ate every cookie, cupcake, dessert, I could get.  Not the whole package (I shared), but enough to get that last taste!  

 

By the time my endoscopy came, I developed intestinal symptoms.  I do not recommend over eating gluten on a challenge!  Well.....maybe!

Reffinej Newbie

Yeah, I'm not feeling great already. I did indulge a wee bit over the weekend (we were away from home, too) but quickly learnt that a) gluten challenge does not equate to an eat-all-rubbish-you-usually-avoid challenge, and gluten, I think, really doesn't agree with me...and I'm starting to look back at much of the sickness I experienced in years gone by and wonder  if gluten played a bigger part that I realised.

      All I can say is this site is great!

      From their website I see "organic barley leaf powder" as an ingredient. Keep in mind that the gluten is in the kernel, and not in the leaves. https://drinkag1.com/about-ag1/ingredients/ctr

      Before the rise of social media we were well known by a lot of doctors and were recommended by many, especially our Safe & Forbidden Lists, but as doctors get younger and younger this is probably not happening as much as before.

      Thanks Scott I will definitely check my vitamins and minerals to see what I am missing so then I can supplement. I was very concern about my Meniers syntoms and i tryed to find some alive. Now im just realizing that my celiac is provably the root cause of my Meniers none of the 12 doctors I saw told me anything about this.  This web site is so helpful, thanks to people like you we can get answers.

      Vitamin D deficiency can contribute to rib pain. Chest pain stemming from the ribs ccould be costochondritis, which involves inflammation of the cartilage connecting the ribs to the breastbone. This pain can range from mild to severe, potentially mimicking heart attack symptoms, and is often worsened by breathing or movement. Other potential causes include muscle strain, rib fractures, or even referred pain from other conditions.  It will also help to chose vegetables low in omega 6.
