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!

      @Jane02, I hear you about the kale and collard greens. I don't do dairy and must eat green leafies, too, to get sufficient calcium. I must be very careful because some calcium supplements are made from ground up crustacean shells. When I was deficient in Vitamin D, I took high doses of Vitamin D to correct the deficiency quickly.

      I do not know this, but since they are labelled gluten-free, and are not really a product that could easily be contaminated when making them (there would be not flour in the air of such a facility, for example), I don't really see contamination as something to be concerned about for this type of product.

      @Jane02, I hear you about the kale and collard greens.  I don't do dairy and must eat green leafies, too, to get sufficient calcium.  I must be very careful because some calcium supplements are made from ground up crustacean shells.  When I was deficient in Vitamin D, I took high doses of Vitamin D to correct the deficiency quickly.  This is safe and nontoxic.  Vitamin D level should be above 70 nmol/L.  Lifeguards and indigenous Pacific Islanders typically have levels between 80-100 nmol/L.   Levels lower than this are based on amount needed to prevent disease like rickets and osteomalacia. We need more thiamine when we're physically ill, emotionally and mentally stressed, and if we exercise like an athlete or laborer.  We need more thiamine if we eat a diet high in simple carbohydrates.  For every 500 kcal of carbohydrates, we need 500-1000 mg more of thiamine to process the carbs into energy.  If there's insufficient thiamine the carbs get stored as fat.  Again, recommended levels set for thiamine are based on minimum amounts needed to prevent disease.  This is often not adequate for optimum health, nor sufficient for people with absorption problems such as Celiac disease.  Gluten free processed foods are not enriched with vitamins like their gluten containing counterparts.  Adding a B Complex and additional thiamine improves health for Celiacs.  Thiamine is safe and nontoxic even in high doses.  Thiamine helps the mitochondria in cells to function.  Thiamine interacts with each of the other B vitamins.  They are all water soluble and easily excreted if not needed. Interesting Reading: Clinical trial: B vitamins improve health in patients with coeliac disease living on a gluten-free diet https://pubmed.ncbi.nlm.nih.gov/19154566/ Safety and effectiveness of vitamin D mega-dose: A systematic review https://pubmed.ncbi.nlm.nih.gov/34857184/ High dose dietary vitamin D allocates surplus calories to muscle and growth instead of fat via modulation of myostatin and leptin signaling https://pubmed.ncbi.nlm.nih.gov/38766160/ Safety of High-Dose Vitamin D Supplementation: Secondary Analysis of a Randomized Controlled Trial https://pubmed.ncbi.nlm.nih.gov/31746327/ Vitamins and Celiac Disease: Beyond Vitamin D https://pmc.ncbi.nlm.nih.gov/articles/PMC11857425/ Investigating the therapeutic potential of tryptophan and vitamin A in modulating immune responses in celiac disease: an experimental study https://pubmed.ncbi.nlm.nih.gov/40178602/ Investigating the Impact of Vitamin A and Amino Acids on Immune Responses in Celiac Disease Patients https://pmc.ncbi.nlm.nih.gov/articles/PMC10814138/

      Thank you so much @knitty kitty for this insightful information! I would have never considered fractionated coconut oil to be a potential source of GI upset. I will consider all the info you shared. Very interesting about the Thiamine deficiency.  I've tracked daily averages of my intake in a nutrition software. The only nutrient I can't consistently meet from my diet is vitamin D. Calcium is a hit and miss as I rely on vegetables, dark leafy greens as a major source, for my calcium intake. I'm able to meet it when I either eat or juice a bundle of kale or collard greens daily haha. My thiamine intake is roughly 120% of my needs, although I do recognize that I may not be absorbing all of these nutrients consistently with intermittent unintentional exposures to gluten.  My vitamin A intake is roughly 900% (~6400 mcg/d) of my needs as I eat a lot of sweet potato, although since it's plant-derived vitamin A (beta-carotene) apparently it's not likely to cause toxicity.  Thanks again!

      Hello, @Jane02,  I take Naturewise D 3.  It contains olive oil.   Some Vitamin D supplements, like D Drops, are made with fractionated coconut oil which can cause digestive upsets.  Fractionated coconut oil is not the same as coconut oil used for cooking.  Fractionated coconut oil has been treated for longer shelf life, so it won't go bad in the jar, and thus may be irritating to the digestive system. I avoid supplements made with soy because many people with Celiac Disease also react to soy.  Mixed tocopherols, an ingredient in Thornes Vitamin D, may be sourced from soy oil.  Kirkland's has soy on its ingredient list. I avoid things that might contain or be exposed to crustaceans, like Metagenics says on its label.  I have a crustacean/shellfish/fish allergy.  I like Life Extension Bioactive Complete B Complex.  I take additional Thiamine B 1 in the form Benfotiamine which helps the intestines heal, Life Extension MegaBenfotiamine. Thiamine is needed to activate Vitamin D.   Low thiamine can make one feel like they are getting glutened after a meal containing lots of simple carbohydrates like white rice, or processed gluten free foods like cookies and pasta.   It's rare to have a single vitamin deficiency.  The water soluble B Complex vitamins should be supplemented together with additional Thiamine in the form Benfotiamine and Thiamine TTFD (tetrahydrofurfuryl disulfide) to correct subclinical deficiencies that don't show up on blood tests.  These are subclinical deficiencies within organs and tissues.  Blood is a transportation system.  The body will deplete tissues and organs in order to keep a supply of thiamine in the bloodstream going to the brain and heart.   If you're low in Vitamin D, you may well be low in other fat soluble vitamins like Vitamin A and Vitamin K. Have you seen a dietician?
