Hi. i'm new here. lots of questions... please bear with me!

1. I'm gluten-free, as i was sick my whole life, nausous every single day, went gluten-free because i was nursing my 18mo, who i wanted gluten-free for neurological purposes, and i felt AMAZING!!! have eaten gluten here and there, and have always felt horrible, so gluten-free i am. got kids tested, and all 3 came up ttg IgG positive, but igA negative. the paper says that "celiac disease is unlikely when igA negative". and their total igA is normal (although on the saliva test, the oldest daughter had a ver depressed igA level, as in non-existant (<5, with reference being 25-60 normal, and 20-25 borderline), so how it came back normal in blood, idk...) pedi gi specialist appt jan 2nd. ***am wondering if anyone has ever heard of someone being ttg igG positive,but EVERY other test on a full celiac panel was negative!!! and still been celiac?***

2. hubby came out positive igA in the saliva test- which he refuses to admit is accurate. (18, with reference being borderline 13-15 and positive >15) i read somewhere that with that result, he has a 97% chance of having celiac disease. opinions?

btw, genetically, 2 girls and i are at high risk of celiac (dq2 heterozygous), hubby is moderate (dq8 heterozygous), and son is extremely low risk (dq2-,dq8-)

3. i had a 12 on the saliva test (with reference being borderline 13-15 and positive >15). this was after 3 years of being almost completely gluten-free. with cheating (a slice of pizza or half of bagel), maybe 1/month or every other month. for the 2 weeks before the test, i ate a slice of pizza, half a bagel, and 3 pieces of general tso chicken (breaded.). that's it. imo, if i ate only that amount, and i was only 1 point away from borderline, i would've probably been glaringly positive had i been eating gluten all along. ***opinions on that please!* several months ago, i ate a little gluten here and a little there, too many times, and all of my symptoms came back with a vengence. i was SO sick. so i went completely 100% gluten-free. i'm SO done with this! now i regret not getting tested when all of my symptoms were back, as i will NEVER do a gluten-challenge after feeling SO sick again! ugh...

any insight into anything i said would be greatly appreciated!!!!! thanks!!!

In terms of genetics, it really doesn't matter as long as you have the genes you have the chance of getting it. Granted i've heard that those with two copies of a gene have more severe reactions.

Low IGA can throw off the testing.

At this point in time, in terms of what you probably have with gluten, is either Celiac or NCGI. Both are similar to one another in reactions (in a sense that gluten is the culprit). Furthermore, you'd have to have a good gluten challenge to be dx'd any further than what you are.

As for the children, are they still on gluten? Do they have reactions?

As for the panel being negative, very possible. I've heard of cases where a person had all the blood tests negative and the biopsy is positive. Likewise, i only scored a positive on the IGA TTG and a negative biopsy (4 weeks gluten free however).

I've never heard of a saliva test. Send him in to get the blood test done to see if it corrosponds.

My son was negative on all IgA tests (but was not deficient) and positive on only the IgG tests. He had zero GI symptoms - his only symptom was an extreme and sudden change in behavior. The first doctor said he did NOT have celiac based on his blood test (and his genetic test said "low possibility" too.) When he couldn't explain the high IgG tests, we took him to the Celiac clinic at Children's Hospital Boston. They did an endoscopy and found extensive celiac damage. Once off gluten, he was back to normal and feeling great.

I got tested too and my IgA test were positive and IgG negative. My endoscopy was negative, but all my (many) symptoms went away within weeks of being gluten free.

The tests are confusing and unreliable. Plenty of people test negative on the IgA tests . . .THATS WHY THE GIVE THE WHOLE PANEL, to catch more people.

shadowicewolf~ kids eat very limited gluten, as the household is gluten-free, because i am, and i"m the cook! lol! i've also noticed meltdown-like behavior when kids eat too much gluten. my oldest daughter (10yo) got facial tics, that went away after she went gluten-free. after about a year, i let her slowly introduce gluten, and after months, tics came back. then went away after being gluten-free. i htink my son (8yo) gets volatile on gluten. and my littlest daughter (5yo) shows no symptoms yet. although i will say that i have them all eating gluten, as i want them all tested in january (and what a better time of year for a gluten-challenge?!), and lately my little girl has been saying that she "doesn't feel right; doesn't feel right in her head; feels like something's missing; feels like something's wrong", and i have a feeling that it's the gluten. we'll see. like is aid they ahve all been found to have igG in their blood. and my oldest was mostly gluten-free for 3 years, ate gluten for only 3 weeks before she got a positive on her igG! but on the whole, my kids can eat gluten, and i do not see any difference in them as far as tummy issues, rashes, etc. but with hubby and me being gluten-sensitve, and us both carrying the genes, i want to catch it in the kids, before it becomes a problem! (if i can!)

thanks so much and if anyone else has something to add, i'd really appreciate it!

Cara~ that is EXACTLY the thing i wanted to hear!!!! that it is possible! i do not want my children to have celiac disease... but if they do have it, then i WANT TO FIND OUT!!!!

this is what my daughter's paper says: "tissue transglutaminase (tTG) has been identified as the endomysial antigen. studies have demonstrated that endomysial igA antibodies have over a 99% specificity for gluten senstive enteropathy". so, what kind of igA did you have positive? because if it is ttg igA, then you most likely have celiac. no matter if they didn't find tissue damage... yet!

      10 years later, my celiac is progressing

      @GardeningForHealth, On my journey, I found following the Autoimmune Paleo Diet most helpful in reducing reactions to various foods.  It's very restrictive, but it really helps improve gut health.  It's worth the effort for a few weeks or months. Tea from any grocery store; Tea, organic; Tea, grown in USA, never-sprayed, loose leaf Tea contains TANNINS which can inactivate Thiamin resulting in Thiamin deficiency.  Tannins inhibit the absorption of other vitamins and minerals, especially iron. Tannins can inactivate digestive enzymes.  So drink tea between meals.  Choose a tea with lower levels of tannin, like green tea or Oolong tea.  Oolong tea contains amino acid Theanine which reduces inflammation in the digestive tract. Dairy; Rice, any brand, even after washing 3 times Many people develop Lactose intolerance because damaged villi in the intestinal lining of the digestive tract cannot produce the enzyme Lactase needed to digest the sugar in dairy, Lactose.   Many people with Celiac Disease react to the protein Casein the same as they react to the protein Gluten.  This is because both Casein and Gluten, as well as the protein in rice, carry a similar segment of a protein building block chain (33 mer peptide) that triggers the autoimmune response in Celiac Disease.  Basmati rice is less likely to carry this protein chain and may be better tolerated.  Don't wash rice before cooking.  The added vitamins get washed away.  Some of those grains of rice are extruded vitamins.  They dissolved into the cooking water and are reabsorbed into the grains as the rice cooks. Organic catchup, Potatoes; Tomatoes are a member of the Nightshade vegetables which have been shown to increase gastrointestinal permeability and "leaky gut syndrome."  Potatoes, Peppers and Eggplant also belong to the Nightshades, and should be avoided until healed.  Catsup usually is acidic which can be irritating to the digestive system. Any and all brands of gluten-free breads and dessert items; Cassava flour; Gluten-free flour Often these contain cross contamination with gluten.  @Scott Adams recently posted a new article about this.  Gluten free products are not enriched with vitamins and minerals needed to digest and process them.  They are high in insoluble fiber and saturated fats.  These may also contain microbial transglutaminase, see below. Sausage, Any processed meat These foods contain microbial transglutaminase, a flavor and texture enhancer, called "meat glue" in the food processing industry, which triggers and provokes anti-gluten antibodies to attack the microbial transglutaminase as well as the tissue transglutaminase produced by our own bodies as with Celiac Disease.  We have articles about microbial transglutaminase, too.  Cassava also contains Thiaminase, an enzyme which destroys Thiamin. Cucumbers from a grocery store, but not from my garden, Most apples, Zucchini, Plums Cucumbers, like these other fruits and veggies, contain lots of soluble fiber, pectin, which intestinal bacteria can ferment and then make short chain fatty acids, which are beneficial.  So that's a good thing.  However, commercially produced breeds of veggies and fruits may contain higher levels of pectins than historically home grown varieties.  Excess consumption of pectins can result in gas, bloating and diarrhea.   Bottled spices  There's an article (perhaps @Scott Adams can help us find, please) about how some spices can cause gastrointestinal symptoms. Gluten-free dairy-free ice cream These can cause reactions if one reacts to oats.  Products made from nuts or nut milks may contain high levels of lectins which are hard to digest and can cause all the usual symptoms.   Smoke from a fire; Strong cleaning chemical fumes These contain Sulfites.  Developing a hyperensitivity to Sulfites is possible in Celiac Disease.  We can be low in vitamins and minerals needed to process Sulfites.  I have Hypersensitivity Type Four where the immune system identifies Sulfites as something to be attacked.  Celiac Disease is another Hypersensitivity Type Four disorder. Packaged sweet potato chips; Packaged plantain chips;  Rice; Any and all brands of gluten-free breads and dessert items; Cassava flour; Gluten-free flour; Gluten-free dairy-free ice cream A High Carbohydrate diet can lead to Small Intestinal Bacterial Overgrowth (SIBO).  Adopting a Paleo diet like the AIP diet is a great way to change your gut biome without using antibiotics which kill off the bad with the good bacteria.  Taking probiotics may not be very effective as long as SIBO bacteria are entrenched in the digestive tract.  You change what you eat and you change what grows inside you.  You starve out the bad SIBO bacteria, repopulate and feed the good ones.  Supplementing with Benfotiamin helps because thiamine has antibacterial properties that keeps the bad bacteria in check and benefits the good bacteria.  Benfotiamin is needed to process all those carbs turning them into energy instead of them turning to fat.   I hope this has been helpful.

      Welcome to the forum @Newhere19! Yes, we have had many forum members that for one reason or another cannot go forward with the confirmation step of the endoscopy with biopsy. Usually it is because they have already been gluten free for a significant period and react so severely to gluten ingestion that they cannot undertake the gluten challenge without endangering their health. But we also have had more than a few who have severe anxiety surrounding the endoscopy itself and cannot bring themselves to go forward with it. May I ask, what was your antibody score or scores, what was the name of the test or tests done and what were the ranges given for normal/negative vs. positive?  What symptoms do you have? What caused you to seek out celiac testing? And to answer your question, many on this forum have had to go forward with the gluten free diet without an official diagnosis for the reasons already stated. You should start seeing symptom improvement within weeks. But realize that achieving a truly free gluten lifestyle is more challenging than most of us realize at the outset. There is a real learning curve involved in order to achieve consistency. That is partly due to the many unexpected places gluten is tucked away in the food supply/supplements/medications and partly because of CC (Cross Contamination) issues. I will offer this primer to get you off to a good start:

      I recently had bloodwork done with a GI specialist and was told that I have celiac.. .but they will not confirm the diagnosis without an endoscopy and biopsy. Due to severe trauma I cannot endure the endoscopy and they made it quite clear full sedation is not an option. So now I have to venture forward assuming this is in fact what is causing all of my symptoms. Has anyone else here had the same experience and started the gluten free diet to see if you're really suffering from celiac? If so, how long did you commit before safely saying the results are accurate? My thought was at least three months would be necessary. Much love to everyone ❤️

      Your experience sounds incredibly challenging and frustrating. It’s impressive that you’ve been so methodical in tracking your triggers and finding safe foods. While it may feel bizarre, sensitivities like these can sometimes point to underlying conditions like chemical sensitivities, histamine intolerance, or even specific food additives. Have you considered consulting with a functional medicine practitioner or allergist who might specialize in these types of issues? You’ve done a lot of the hard work already with your food diary, and that could provide valuable insights for a professional to help you further.
