Positive For Allergies But Negative For Celiac?


MissCici

I had a skin test two weeks ago for food allergies and discovered that, among many other things, I'm allergic to wheat, yeast, barley, rice, potatoes, etc. Today, they called to say that I was negative for Celiac Disease. I know that my diet will be the same either way, but with all the related allergies, I'm curious why the gluten didn't show up. Also, the blood work they ran to confirm the allergies was very inaccruate - it showed no allergies to foods I've had a reaction to. The nurse told me that the blood test isn't as accurate and to go off the skin test since it confirmed some foods I had a known allergy to. Should I trust the negative on the Celiac? It seems that it is frequently misdiagnosed or shows a false negative.

Thanks!

Cici

Cici, hello and welcome. :)

Yes, there is often a false negative for celiac tests.

I am of the opinion that diet alone can be used as a diagnostic tool.

It sounds like you are having a lot of reactions, do you have a sense of what else might be causing them?

I can't eat grains, dairy, nightshades, sugar, coffee..... for me it is related to Celiac (a brother and sister diagnosed with Celiac so I am either Celiac or gluten intolerant) and Lyme but that is all tangled up with Candida and mercury toxicity. :(

I've been on this board for just over a year now and have found it incredibly helpful. I'm also feeling much better after being gluten, dairy, etc. free for the past year. Okay, I cheat occasionally with strawberry Hagan Daas. :) Well and a little coffee. :ph34r::lol:

All questions are good questions.

My experience with allergy testing for my pollen/enviornmental allergies is that the skin test is far more accurate. So I agree with your nurse. I move around a lot, and have to get periodically retested and have my shot adjusted. The one doctor who used a bood test, the shots didn't work at all. They grudgingly retested with a skin test, and the results were radically different, and the resulting shots worked much better.

There are a lot of false negatives with blood allergy testing, and from what I gather, since I'm new here, is it is the same with the Celiac blood testing.

Listen to your bod. :)

I went to an allergist about 2 years ago, and had the skin test, and tested positive for chicken, wheat, soy, tree nuts and fish. That's interesting that you're all saying that the skin test is more accurate. I had always heard that the blood test was more accurate. The allergist also told me that the wheat, soy and chicken reaction wasn't that big (it was a 1) but the tree nuts and fish was a 2 so he just said to stay away from the latter 2 things. But every time I eat bread, breaded things, things fried in oil (soy) I get sick--within an hour.

I just today decided to go back on a wheat free diet , and chicken, fish, soy, and tree-nut free diet and see if that works better. It's really hard though, because the only things I can afford are fresh fruits and veggies. I'm on disability and unemployed, so not much more than 30.00 a week allotted for food.

celiac disease is not an allergy - the allergy tests don't even look for it.

Yeah, I know the difference, believe me. I spent hours and hours on the computer researching it 2 years ago. I either have celiac, or just a wheat allergy, which is what I thought I said but I guess I didn't. But I think I have a wheat allergy rather than celiac, just from my symptoms. But the result is the same, stay away from wheat/gluten.

sorry if it wasn't clear in my post, and it doesn't help that we don't have any note of hierarchical structure while maintaining view of all the posts, but my response was to the OP (original poster). it's one of the things that can be a bit difficult to read about the site - who's responding to whom. :shrug:

drewsant Rookie

Sorry, I wondered that after I posted, when I went back and read the posts again.

Sorry if I wasn't clear - they tested me for both allergies and Celiac. The allergies are definate based on the skin test. The blood on the Celiac came back normal, but I've read that those results aren't always accurate. Although they are different, I think that it's odd that the allergies can be so strong (3s or 4s on the scratch test), with the Celiac being normal. It's seems as though there would be a high correlation between the two.

Everything that I've read indicates that allergy and celiac are two different reactions to the wheat/gluten. The symptoms can be the same, the treatment essentially the same (don't eat it), but the underlying mechanism is different.

You can be both, neither or one without the other.

      Welcome to the forum, @Judy M! Yes, he definitely needs to continue eating gluten until the day of the endoscopy. Not sure why the GI doc advised otherwise but it was a bum steer.  Celiac disease has a genetic component but also an "epigenetic" component. Let me explain. There are two main genes that have been identified as providing the "potential" to develop "active" celiac disease. We know them as HLA-DQ 2.5 (aka, HLA-DQ 2) and HLA-DQ8. Without one or both of these genes it is highly unlikely that a person will develop celiac disease at some point in their life. About 40% of the general population carry one or both of these two genes but only about 1% of the population develops active celiac disease. Thus, possessing the genetic potential for celiac disease is far less than deterministic. Most who have the potential never develop the disease. In order for the potential to develop celiac disease to turn into active celiac disease, some triggering stress event or events must "turn on" the latent genes. This triggering stress event can be a viral infection, some other medical event, or even prolonged psychological/emotional trauma. This part of the equation is difficult to quantify but this is the epigenetic dimension of the disease. Epigenetics has to do with the influence that environmental factors and things not coded into the DNA itself have to do in "turning on" susceptible genes. And this is why celiac disease can develop at any stage of life. Celiac disease is an autoimmune condition (not a food allergy) that causes inflammation in the lining of the small bowel. The ingestion of gluten causes the body to attack the cells of this lining which, over time, damages and destroys them, impairing the body's ability to absorb nutrients since this is the part of the intestinal track responsible for nutrient absorption and also causing numerous other food sensitivities such as dairy/lactose intolerance. There is another gluten-related disorder known as NCGS (Non Celiac Gluten Sensitivity or just, "gluten sensitivity") that is not autoimmune in nature and which does not damage the small bowel lining. However, NCGS shares many of the same symptoms with celiac disease such as gas, bloating, and diarrhea. It is also much more common than celiac disease. There is no test for NCGS so, because they share common symptoms, celiac disease must first be ruled out through formal testing for celiac disease. This is where your husband is right now. It should also be said that some experts believe NCGS can transition into celiac disease. I hope this helps.

      My husband has had lactose intolerance for his entire life (he's 68 yo).  So, he's used to gastro issues. But for the past year he's been experiencing bouts of diarrhea that last for hours.  He finally went to his gastroenterologist ... several blood tests ruled out other maladies, but his celiac results are suspect.  He is scheduled for an endoscopy and colonoscopy in 2 weeks.  He was told to eat "gluten free" until the tests!!!  I, and he know nothing about this "diet" much less how to navigate his in daily life!! The more I read, the more my head is spinning.  So I guess I have 2 questions.  First, I read on this website that prior to testing, eat gluten so as not to compromise the testing!  Is that true? His primary care doctor told him to eat gluten free prior to testing!  I'm so confused.  Second, I read that celiac disease is genetic or caused by other ways such as surgery.  No family history but Gall bladder removal 7 years ago, maybe?  But how in God's name does something like this crop up and now is so awful he can't go a day without worrying.  He still works in Manhattan and considers himself lucky if he gets there without incident!  Advice from those who know would be appreciated!!!!!!!!!!!!

      You've done an excellent job of meticulously tracking the rash's unpredictable behavior, from its symmetrical spread and stubborn scabbing to the potential triggers you've identified, like the asthma medication and dietary changes. It's particularly telling that the rash seems to flare with wheat consumption, even though your initial blood test was negative—as you've noted, being off wheat before a test can sometimes lead to a false negative, and your description of the other symptoms—joint pain, brain fog, stomach issues—is very compelling. The symmetry of the rash is a crucial detail that often points toward an internal cause, such as an autoimmune response or a systemic reaction, rather than just an external irritant like a plant or mites. I hope your doctor tomorrow takes the time to listen carefully to all of this evidence you've gathered and works with you to find some real answers and effective relief. Don't be discouraged if the rash fluctuates; your detailed history is the most valuable tool you have for getting an accurate diagnosis.

      In this case the beer is excellent, but for those who are super sensitive it is likely better to go the full gluten-free beer route. Lakefront Brewery (another sponsor!) has good gluten-free beer made without any gluten ingredients.

      Welcome to the forum, @catsrlife! Celiac disease can be diagnosed without committing to a full-blown "gluten challenge" if you get a skin biopsy done during an active outbreak of dermatitis herpetiformis, assuming that is what is causing the rash. There is no other known cause for dermatitis herpetiformis so it is definitive for celiac disease. You would need to find a dermatologist who is familiar with doing the biopsy correctly, however. The samples need to be taken next to the pustules, not on them . . . a mistake many dermatologists make when biopsying for dermatitis herpetiformis.
