York Test Results

Hi,

I just got the results from my York blood test.I have been advised to avoid cow's milk, yeast, corn, egg whites, and wheat. :(

The foods with no reaction include barley, gliadin(gluten),oats, and rye. :unsure:

I take that to mean I have a wheat (not gluten) intolerance. This next statement is the one that confuses me "Those with wheat intolerance will still experience adverse symptoms from gluten-free products, as the remaining part of the wheat will be effecting them. They may, or may not be able to eat rye, barley, and oats, that are part of the wheat family and as with many other food intolerances, may be able to reintroduce wheat back into the diet after a period of elimination."My question is are they saying that gluten-free products can contain wheat with the gluten protein removed? Can someone explain this to me, I can't quite get my head around it? <_<

Any or all comments will be appreciated.

don't take the test results as gospel. my husband got similar results and his gastro told him to take with big grain of salt; and quite possibly it could be bogus. go to Quackwatch.com for list of tests that are not considered reliable. This is one of them, as it appears on Quackwatch.

I thought York was supposed to be one of the good labs? What test did they run on your blood to come to that conclusion?

It was a 113 food IgG ELISA In Depth Panel. I'm going to try to follow it because I knew I had a problem with wheat and dairy. I was surprised about the corn, egg whites. Yeast doesn't surprise me because I have an allergy to mold. Corn syrup is in a lot of foods. I did the test because I was having right -sided pain and having trouble losing weight. I have lost 20lbs but I need to lose at least 20 more. My GI doc poo-poo'd it but I need to feel better, I'm still having trouble sleeping and I'll try anything to get better. ;)

I've heard York to be a good testing and one of my doctors even recommended me getting one done(before they knew it was celiac) Some doctors just don't like it and are close minded and they will make every excuse in the book not to get it done.

York tests for IgG antibodies. These abate after a period of time of allergen abstinance, so if you have been gluten free, they may be lower for wheat. They don't test for IgA, which is the better indicator of celiac disease as well as EMA and TtG. You know you have a gluten problem (i.e. celiac disease), so continue to stay gluten-free for life. If you only had a "wheat allergy" and not an auto-immune reaction, you might be able to resume wheat after a period of time. The comment about wheat in gluten-free products concerns the use of Codex wheat starch in europe, supposedly safe for celiacs. If you have a wheat allergy, it isn't safe despite its lack of/low gluten content.

Thanks Kvogt. Your answer makes sense to me. It's funny that I have been gluten-free for over a year and I'm still reacting to wheat, it wasn't as strong as the dairy and yeast but definitely needs to be avoided. I'm going to stay gluten free for life but I would someday like to do an elimination diet for dairy. Thanks for all of the comments, if this test is not valid then why do so many people feel better after avoiding the offending foods?

I think it is valid :D ...I was recommended by my doc as I said earlier...alot of people have these testings done. I think some doctors exed it off from day one because of their way of thinking.

Why I feel that York is at least questionnable:

1) My husband was diagnosed IBS since 1977 has never eaten the following in all this time and York said he was sensitive to these foods: Nuts: Cashew, brazil, hazelnut, almond; Lentils (that's a laugh); chili pepper (that's even funnier); garlic. So based on the theory that if you avoid something for a while, you should not get antibodies to it, then the York test is wrong.

2) He also tested posiitve with York for wheat and at that point he was doing gluten-free for 8 months. That one I'll be open minded about. But the other foods have not been consumed by him since 1977; so how can he have anti bodies to something he hasn't eaten in those many years.

3) We did the 113 Food IgG ELISA test on our own. The gastro doctor saw the results and wasn't impressed and told us not to put too much value on them.

I did see this ELISA test spoken about on Quackwatch.com. When someone is ill, it's easy to try anything to feel better and I'd hate to have companies preying on celiacs and promoting things which are questionnable.

To Judy05 only: just a thought - see ob/gyn about your right-sided pain to rule out that type of problem.

Judy05, Right-side pain? Have you been tested for gall bladder or appendix problems?

I've been tested 4 times for GB problems. This usually occurs if I eat too much fruit

I know it's not appendix, I'm a nurse and the pain is not in that area. A long time ago I was diagnosed with dyskinesia which is a spasm in the common duct, there is a procedure to relieve that but it hasn't shown up on my test again. Of course the doctor won't do anything without proof.

I'm not surprised that wheat is still showing up, it's almost impossile to be completely gluten-free, we all have accidents. I know someone who didn't get better for a full 3 years after being diagnosed. I'm not sure how they test, I know some of the foods that I had no reaction to I have never eaten. Maybe they test to see how you would react if you did eat them? I'm amazed how they could test for 113 foods with such a small amount of blood.I'm going to try sticking to the test results for at least 2-3 months. I always knew I had a problem with wheat, dairy, and yeast. The eggs whites and corn were a suprise but they are not uncommon allergens.

I called York about the test results and asked specifically why a food sensitvity would show up when it wasn't consumed in years.

They told me that they test for antibodies for the food. If you don't consume that particular food, you won't have antibodies for it. I would presume that after not eating something for over 20 years you should not have anti bodies in your bloodstream for that item. That's why I am unconvinced this test is accurate.

My husband has not had those nuts; not even in oil form (as they suggested); he hasn't had lentils since 1978 about; he eats his food plain and at time of test, had not eaten out in restaurant in over 8 mos. Very perplexing to me.

Deb, the life of antibodies vary a lot. Some viral and bacterial diseases we are immune to for the rest of our lives and others we are not. I know they (especially viruses) change rapidly so we have to get yearly vaccines for some and not others, but in general how long antibodies stay around in your body varies a lot so these antibodies could show up for years after not eating the item and contamination especially with nuts is so common that they could help keep antibody levels present in your blood even if we haven't had them in a long time. To explain lifelong immunity, scientists believe that there is some antigen (so some nut proteins or viral proteins) library in the thymus and they periodically cause reactivation of antibodies so we get life long immunity even to things that are not harmful and without exposure. I will try to find out more because I am having the same questions.

But if we follow the theory, after long term avoidance of the food, the food should be re-introduced and the sensitivity should be gone. I can under stand cross contamination of nut products, but not the lentils. My jury is stilll out on this issue.

I think the sensitivity MAY be gone and not should be gone. It depends on the immune response mounted. Antibodies do cross react so maybe there is some cross reaction going on so your husband has some antibodies that are reacting to their lentil antigen? Just a thought.

They use IgG Elisas to test food allergies in animals all the time. It is standard.

I'm sorry I don't think quackwatch.com is a reliable source.

They offer IgG and IgE Elisa food allergy testing. Thought that was cool because food allergies are not only mediated by IgG that york tests for.

      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?
