"What is a gluten challenge?

A gluten challenge is the period of time when gluten is added back into a person’s diet to assist in the diagnosis of celiac disease. Antibodies take time to build into the blood stream before they can be detected through blood analysis. For a gluten challenge we recommend eating 1/2 slice of bread or a cracker each day for the duration of the challenge.

  • Prior to blood testing we recommend 12 weeks of eating gluten.
  • Prior to an endoscopic biopsy we recommend 2 weeks of eating gluten.

In the case of a severe reaction to gluten, a medical professional may opt to shorten the 12-week challenge and move immediately to an endoscopic biopsy."

I've been eating gluten for pretty much my entire life except for these past 2 weeks which I've decided to go glutenfree to potentially help another autoimmune disease I have. But now I'm curious as to whether I really have Celiac so I'm thinking to go in for a blood test. Do I have to continue eating gluten for the next 12 weeks, or it is okay to just go in now since I've only been gluten free for a short amount of time?

No one can really say.  Lots of people still have high antibodies after a few months gluten-free.  Its hard to know how your body is reacting.

I would continue to eat it and get blood tested (as already described by Karen) to be sure. If the test were negative would you always wonder if it was a false negative? I would... just a thought.

      Basic metabolic panel results - more flags

      Thank you @trents for letting me know you experience something similar thanks @knitty kitty for your response and resources.  I will be following up with my doctor about these results and I’ll read the articles you sent. Thanks - I really appreciate you all.

      You're right, doctors usually only test Vitamin D and B12.  Both are really important, but they're not good indicators of deficiencies in the other B vitamins.  Our bodies are able to store Vitamin B12 and Vitamin D in the liver for up to a year or longer.  The other B vitamins can only be stored for much shorter periods of time.  Pyridoxine B 6 can be stored for several months, but the others only a month or two at the longest.  Thiamine stores can be depleted in as little as three days.  There's no correlation between B12 levels and the other B vitamins' levels.  Blood tests can't measure the amount of vitamins stored inside cells where they are used.  There's disagreement as to what optimal vitamin levels are.  The Recommended Daily Allowance is based on the minimum daily amount needed to prevent disease set back in the forties when people ate a totally different diet and gruesome experiments were done on people.  Folate  requirements had to be updated in the nineties after spina bifida increased and synthetic folic acid was mandated to be added to grain products.  Vitamin D requirements have been updated only in the past few years.   Doctors aren't required to take as many hours of nutritional education as in the past.  They're educated in learning institutions funded by pharmaceutical corporations.  Natural substances like vitamins can't be patented, so there's more money to be made prescribing pharmaceuticals than vitamins.   Also, look into the Autoimmune Protocol Diet, developed by Dr. Sarah Ballantyne, a Celiac herself.  Her book The Paleo Approach has been most helpful to me.  You're very welcome.  I'm glad I can help you around some stumbling blocks while on this journey.    Keep me posted on your progress!  Best wishes!

      So interesting that you stated you had sub clinical vitamin deficiencies. When I was first diagnosed with celiac disease (silent), the vitamin levels my doctor did test for were mostly within normal range (lower end) with the exception of vitamin D. I believe he tested D, B12, magnesium, and iron.  I wondered how it was possible that I had celiac disease without being deficient in everything!  I’m wondering now if I have subclinical vitamin deficiencies as well, because even though I remain gluten free, I struggle with insomnia, low energy, body aches, etc.  It’s truly frustrating when you stay true to the gluten-free diet, yet feel fatigued most days. I’ll definitely try the B-complex, and the Benfotiamine again, and will keep you posted. Thanks once again!

      Has anyone had terrible TMJ/ Jaw Pain from undiagnosed Celiac?

      Segments of the protein Casein are the same as segments of the protein strands of gluten, the 33-mer segment.   The cow's body builds that Casein protein.  It doesn't come from wheat.   Casein can trigger the same reaction as being exposed to gluten in some people.   This is not a dairy allergy (IGE mediated response).  It is not lactose intolerance.
