Igg Testing-- Reliable Or Not Worth The Money?

My biopsy and bloodwork for celiac have come back negative, but I have almost all of the classic symptoms. I have started to look into IgG/ Food sensitivity testing. I have heard and found mixed things.. Did anyone have luck with these tests? I think one of the things I am worried about is false positivies... I don't want to have to stop eating things that really don't make a difference! Are some labs better and more reliable than others? I have talked to a doctor who uses Genova, and one who uses Alletess. Supposedly they can each also test for celiac or at least gluten sensitivity with IgG methods. Thoughts or experiences are much appreciated!

Thanks!

I did the yorktest, and yeast showed up high, and kiwi. Beans and molluscs showed up low. The yeast thing was confirmed by kinesiology. I had been off gluten for 9 months so it did not show up (there si antigliadin IgG in that test)

Some only have IgM reactions.

I guess that a combined test for IgG and IgM would be better (if the lab is realibale. Meaning that if one sends in split samples (slpit the blood and send it in as two different names) show exactly the same result).....this is a problem in some labs. Yorktest is said to have passed that test.

Even though your tests came back negative I would strongly advise that you do the diet strictly for at least a few months. If your celiac testing was a false negative your body may be in hyperdrive, immune system wise and you may find yourself reactive to a lot of foods because of the fact that you need to eliminate gluten. I am someone who always has shown negative (although I recently found a very old celiac screen test where I was a low postive but the doctor had called it a negative because it was only 2 points into positive range so make sure you check the actual lab results don't just go with what the doctor tells you) I had conventional skin testing for allergies before I was diagnosed. I was allergic to everything but beech trees. This was when the allergist prescribed an elimination diet and my celiac was finally found. Turned out I was only really allergic to a couple of items every other allergy fell off after I had been gluten-free for a couple of months.

I'm wondering about these tests, too. I had an anaphylactic-like reaction the last time I ate wheat, and went to a regular allergist, who didn't believe me. She tested me for all sorts of allergies, and I had tons of inhalant allergies which I did'nt know about, but no food allergies. She said the IgG tests were unreliable. So now I'm just walking around wondering if it was wheat or some other thing. I have 3 kids which I wonder about too. I keep wanting to do an elimination diet, but it's hard with kids, they are such picky eaters. Having a test done would at least give me a starting point. The tests are so expensive, though. I was looking at the Lame Advertisement test. If anyone tries any of these tests, let us know if they seemed accurate. Maybe I'll go ahead and try.

Oops, I didn't mean lame advertisement test. I wrote a-l-c-a-t. Didn't know it was a bad word!

      Taken Seriously

      By Scott Adams · Posted

      Your post demonstrates the profound frustration and isolation that so many in the Celiac community feel, and I want to thank you for channeling that experience into advocacy. The medical gaslighting you endured for decades is an unacceptable and, sadly, a common story, and the fact that you now have to "school" your own GI specialist speaks volumes about the critical lack of consistent and updated education. Your idea to make Celiac Disease a reportable condition to public health authorities is a compelling and strategic one. This single action would force the system to formally acknowledge the prevalence and seriousness of the disease, creating a concrete dataset that could drive better research funding, shape medical school curricula, and validate the patient experience in a way that individual stories alone often cannot. It is an uphill battle, but contacting representatives, as you have done with Adam Gray, is exactly how change begins. By framing it as a public health necessity—a matter of patient safety and protection from misdiagnosis and neglect—you are building a powerful case. Your voice and your perseverance, forged through thirty years of struggle, are exactly what this community needs to ensure that no one else has to fight so hard just to be believed and properly cared for.

      I had no idea there is a "Louisville" in Colorado!😉 I thought it was a typo because I always think of the Kentucky city--but good luck!

      Allergy medication: cetirizine by the HealthA2Z is it gluten free?

      By Scott Adams · Posted

      Navigating medication safety with Celiac disease can be incredibly stressful, especially when dealing with asthma and severe allergies on top of it. While I don't have personal experience with the HealthA2Z brand of cetirizine, your caution is absolutely warranted. The inactive ingredients in pills, known as excipients, are often where gluten can be hidden, and since the FDA does not require gluten-free labeling for prescription or over-the-counter drugs, the manufacturer's word is essential. The fact that you cannot get a clear answer from Allegiant Health is a significant red flag; a company that is confident its product is gluten-free will typically have a customer service protocol to answer that exact question. In situations like this, the safest course of action is to consider this product "guilty until proven innocent" and avoid it. A better alternative would be to ask your pharmacist or doctor to help you identify a major national brand of cetirizine (like Zyrtec) whose manufacturer has a verified, publicly stated gluten-free policy for that specific medication. It's not worth the risk to your health when reliable, verifiable options are almost certainly available to you. You can search this site for USA prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/

      Protein or fat?

      By Scott Adams · Posted

      What you're describing is indeed familiar to many in the Celiac community, especially in the early stages of healing. When the intestinal villi are damaged from Celiac disease, they struggle to properly digest and absorb fats, a condition known as bile acid malabsorption. This can cause exactly the kind of cramping and spasms you're seeing, as undigested fats can irritate the sensitive gut lining. It is highly plausible that her reactions to dairy and eggs are linked to their higher fat content rather than the proteins, especially since she tolerates lean chicken breast. The great news is that for many, this does improve with time. As her gut continues to heal on a strict gluten-free diet, her ability to produce the necessary enzymes and bile to break down fats should gradually return, allowing her to slowly tolerate a wider variety of foods. It's a slow process of healing, but your careful approach of focusing on low-fat, nutrient-dense foods like seeds and avocado is providing her system the best possible environment to recover. Many people with celiac disease, especially those who are in the 0-2 year range of their recovery, have additional food intolerance issues which could be temporary. To figure this out you may need to keep a food diary and do an elimination diet over a few months. Some common food intolerance issues are dairy/casein, eggs, corn, oats, and soy. The good news is that after your gut heals (for most people who are 100% gluten-free this will take several months to two years) you may be able to slowly add some these items back into your diet after the damaged villi heal. This article may be helpful: Thank you for sharing your story—it's a valuable insight for other parents navigating similar challenges.

      Diagnosed celiac for 1-2 months ago and everything makes me bloated.

      By Beverage · Posted

      I had a very rough month after diagnosis. No exaggeration, lost so much inflammatory weight, I looked like a bag of bones, underneath i had been literally starving to death. I did start feeling noticeably better after a month of very strict control of my kitchen and home. What are you eating for breakfast and lunch? I ignored my doc and ate oats, yes they were gluten free, but some brands are at the higher end of gluten free. Lots of celics can eat Bob's Red Mill gluten-free oats, but not me. I can now eat them, but they have to be grown and processed according to the "purity protocol" methods. I mail order them, Montana Gluten-Free brand. A food and symptoms and activities log can be helpful in tracking down issues. You might be totally aware, but I have to mention about the risk of airborne gluten. As the doc that diagnosed me warned . . Remember eyes, ears, nose, and mouth all lead to your stomach and intestines.  Are you getting any cross contamination? Airborne gluten? Any pets eating gluten (they eat it, lick themselves, you pet them...)? Any house remodeling? We live in an older home, always fixing something. I've gotten glutened from the dust from cutting into plaster walls, possibly also plywood (glues). The suggestions by many here on vitamin supplements also really helped me. I had some lingering allergies and asthma, which are now 99% gone. I was taking Albuterol inhaler every hour just to breathe, but thiamine in form of benfotiamine kicked that down to 1-2 times a day within a few days of starting it. Also, since cutting out inflammatory seed oils (canola, sunflower, grapeseed, etc) and cooking with real olive oil, avocado oil, ghee, and coconut oil, I have noticed even greater improvement overall and haven't used the inhaler in months! It takes time to weed out everything in your life that contains gluten, and it takes awhile to heal and rebuild your health. At first it's mentally exhausting, overwhelming, even obsessive, but it gets better and second nature.
