I need to get tested for celiacs but im not sure if the results will come up positive since i have been gluten free for over two years, my GP has suggested that i get a stomach biopsy but is not sure if i will be tested positive as i cannot activly eat gluten. I need to get tested so that i can get my food subsidised by the NZ govt.

are there any tests that will show that i am without me having to activly eat gluten?

Do they do mucosal challenges in NZ? Those are a test where they use either a rectal suppository or apply gluten to the mucous membranes in the mouth. Then they wait a couple of hours and biopsy the mucosal tissue and look for a reaction. This is not a test that is done in the US and I don't know what countries use this test. Your only other option is to do a traditional challenge with eating gluten for 3 to 6 months and then doing the blood tests and endoscopic biopsy. If you have been gluten free for 2 years the blood tests and endo biopsy will come back negative even if you do have the disease because being gluten free will stop the antibody production that they look for in blood tests and the villi will have healed giving a false negative.

Another thing to think about is what tests are recognized by the NZ health department or the evaluators who will review your case. That might be worth a phone call or letter to them to get a list of valid tests. And it seems to me maybe discussing your situation with them is worthwhile anyway. They may have run into similar situations and have some way of handling them that you can explore. Since the standard celiac disease treatment is to stop eating gluten, which makes the usual tests invalid, it is kind of a catch-22 situation. Nonetheless, they may accept something from your doctor like a letter or previous medical history?

      Gluten-Free Diet Linked to Reduced Inflammation and Improved Outcomes in Multiple Sclerosis (+Video)

      I worried at one point on my journey whether I had MS, having many of the symptoms myself. However, my symptoms improved dramatically with high dose thiamine hydrochloride, Benfotiamine, and Thiamine TTFD. Thiamine deficiency symptoms overlap with MS symptoms, including changes on brain MRIs. Thiamine deficiency affected my eyes (light sensitivity),...

      Unexpected gluten exposure risk from cultivated mushrooms

      Welcome to the celiac.com communiuty, @Matthias! Yes, we have been aware that this can be an issue with mushrooms but as long as they are rinsed thoroughly it should not be a problem since the mushrooms don't actually incorporate the gluten into their cellular structure. For the same reason, one needs to be careful when buying aged cheeses and products...

      Unexpected gluten exposure risk from cultivated mushrooms

      The one kind of food I had been buying and eating without any worry for hidden gluten were unprocessed veggies. Well, yesterday I discovered yet another pitfall: cultivated mushrooms. I tried some new ones, Shimeji to be precise (used in many asian soup and rice dishes). Later, at home, I was taking a closer look at the product: the mushrooms were growing...

      how much gluten do I need to eat before blood tests?

      I might suggest you consider buckwheat groats. https://www.amazon.com/Anthonys-Organic-Hulled-Buckwheat-Groats/dp/B0D15QDVW7/ref=sr_1_4_pp?crid=GOFG11A8ZUMU&dib=eyJ2IjoiMSJ9.bk-hCrXgLpHqKS8QJnfKJLKbKzm2BS9tIFv3P9HjJ5swL1-02C3V819UZ845_kAwnxTUM8Qa69hKl0DfHAucO827k_rh7ZclIOPtAA9KjvEEYtaeUV06FJQyCoi5dwcfXRt8dx3cJ6ctEn2VIPaaFd0nOye2TkASgSRtdtKgvXEEXknFVYURBjXen...

      IBS-D vs Celiac

      What you’re describing really does not read like typical IBS-D. The dramatic, rapid normalization of stool frequency and form after removing wheat, along with improved tolerance of legumes and plant foods, is a classic pattern seen in gluten-driven disease rather than functional IBS. IBS usually worsens with fiber and beans, not improves. The fact that y...

Yes, we have been aware that this can be an issue with mushrooms but as long as they are rinsed thoroughly it should not be a problem since the mushrooms don't actually incorporate the gluten into their cellular structure. For the same reason, one needs to be careful when buying aged cheeses and products containing yeast because of the fact that they are sometimes cultured on gluten-containing substrate.

      The one kind of food I had been buying and eating without any worry for hidden gluten were unprocessed veggies. Well, yesterday I discovered yet another pitfall: cultivated mushrooms. I tried some new ones, Shimeji to be precise (used in many asian soup and rice dishes). Later, at home, I was taking a closer look at the product: the mushrooms were growing from a visible layer of shredded cereals that had not been removed. After a quick web research I learned that these mushrooms are commonly cultivated on a cereal-based medium like wheat bran. I hope that info his helpful to someone.

Incidentally, I don't like quinoa either. Reminds me and smells to me like wet grass seed. When its not washed before cooking it makes me ill because of saponins in the seed coat. Yes, it can be difficult to get much dietary calcium without dairy. But in many cases, it's not the amount of calcium in the diet that is the problem but the poor uptake of it. And too much calcium supplementation can interfere with the absorption of vitamins and minerals in general because it raises gut pH.

      IBS-D vs Celiac

      By Scott Adams · Posted

      What you’re describing really does not read like typical IBS-D. The dramatic, rapid normalization of stool frequency and form after removing wheat, along with improved tolerance of legumes and plant foods, is a classic pattern seen in gluten-driven disease rather than functional IBS. IBS usually worsens with fiber and beans, not improves. The fact that you carry HLA-DQ2.2 means celiac disease is absolutely possible, even if it’s less common than DQ2.5, and many people with DQ2.2 present later and are under-diagnosed. Your hesitation to reintroduce gluten is completely understandable — quality of life matters — and many people in your position choose to remain strictly gluten-free and treat it as medically necessary even without formal biopsy confirmation. If and when you’re ready, a physician can help you weigh options like limited gluten challenge, serology history, or documentation as “probable celiac.” What’s clear is that this wasn’t just random IBS — you identified the trigger, and your body has been very consistent in its response.
