Allergy And Blood Testing Questions

I am new to the Celiac/gluten allergy issues. I began having sharp stomach pains about 2 months ago followed by hives 10 to 15 minutes after pretty much every meal. The hives were so bad that I went into anaphylactic shock on two separate occasions. After several visits with my primary care doctor, I was sent to an allergist. I began doing my own research on Celiac after determining that it was the common factor in every meal I ate. As I did my research on Celiac, I found I had several symptom including bouts that varied between diarrhea/constipation, bloating, post nasal drip, frequent sinus infections, episodes of asthma related symptoms, chronic fatigue, foggy brain.

The allergist started me on two different nasal sprays for the nasal allergies and set me up for allergy testing. His thought was the hives were more likely related to environmental allergies. This did not seem to make sense to me as nothing had changed in my environment to cause the hives! Since seeing the allergist, I have cut out all gluten in my diet and the hives have stopped.

I am trying to understand Celiac and gluten allergy. I have eaten an abnormally high amount of carbs (3 pieces of sliced bread was a normal after school snack) my entire life without issue. I've noticed I have several of the associated diseases to Celiac including asthma, endometriosis, and hypothyroid. Since becoming pregnant with my daughter (who is now 1) I had a iron deficiency and a vitamin D deficiency. I'm wondering if my pregnancy caused the change in allergens.

 

My questions:

1) Will the allergy testing (my understanding is it is skin testing) be affected by my gluten free diet causing either a false positive or a false negative? If so, should I re-introduce gluten into my diet?

2) I am going to ask my doctor for the blood test that is preliminary to a Celiac diagnosis. Will my gluten free diet affect that test causing skewed results?

3) Is it possible for someone to develop an allergy/intolerance to gluten or wheat?

 

I am extremely appreciative of any help in understanding what is going on and suggestions for types of specialists to see to help.

1. Allergy testing? No, that will not effect it. The allergy test is generally a skin prick test where they use a needle to inject a small amount of whatever element they are testing for under the skin and wait to see if a hive develops.

 

2. Yes, yes, and yes. In order for any blood work to come back positive, you must be consuming gluten. There is debate on how long this period must be.

 

3. Yes. It can be triggered by an event (such as pregnancy, an illness, or surgery).

Celiac disease is not an allergy. Anaphylactic shock is not usually associated with Celiac, it is an allergic reaction. You can have Celiac and a wheat allergy or any other allergy. You need to be eating gluten to test for Celiac. The blood test looks for antibodies to gluten. You do not produce enough antibodies to gluten to show in a blood test if you are not eating gluten.

      Edy's and Dreyer's ice cream

      By Aretaeus Cappadocia · Posted

      Sigh. I posted this yesterday based on the Safeway website. I went back again today to their website to double check. On the page where they are selling Vanilla Bean flavor, it has a distinct Certified Gluten Free label. Other flavors on the Safeway website didn't have the gluten-free statement. Today I went into the store. None of the flavors I looked at, including Vanilla Bean, have a Gluten Free statement. Is it safe? Who knows. The ingredients are either safe or nearly safe (some have "natural flavor"). There are warnings about "contains milk and soy" but not about wheat - this implies they are safe, but again, who knows. On the other hand, every flavor I checked of their Slow Churn line of ice creams has wheat as an ingredient. 100% not safe.

      Do keep in mind that many of the newly diagnosed have lactose intolerance.  This is because the villi lining the intestinal tract are damaged, and can no longer make the enzyme lactAse which breaks down the milk sugar lactOse.  When the villi grow back (six months to two years), they can again produce the enzyme lactAse, and lactose intolerance is resolved.  However, some people (both those with and without Celiac Disease) are genetically programmed to stop producing lactase as they age.   Do be aware that many processed foods, including ice cream, use Microbial Transglutaminase, a food additive commonly called "meat glue," used to enhance texture and flavor.  This microbial transglutaminase has the same immunogenicity as tissue transglutaminase which the body produces in response to gluten in people with Celiac Disease.  Tissue Transglutaminase (tTg IgA) is measured to diagnose Celiac Disease in blood tests.  Microbial Transglutaminase acts the same as Tissue Transglutaminase, causing increased intestinal permeability and inflammation.   New findings show that microbial transglutaminase may be able to trigger Celiac Disease and other autoimmune and neurodegenerative diseases.   Microbial Transglutaminase is not required to be listed on ingredients labels as it's considered a processing aid, not an ingredient in the U.S.  Microbial Transglutaminase has been GRAS for many years, but that GRAS standing is being questioned more and more as the immunogenicity of microbial transglutaminase is being discovered. Interesting Reading:  Microbial Transglutaminase Is a Very Frequently Used Food Additive and Is a Potential Inducer of Autoimmune/Neurodegenerative Diseases https://pmc.ncbi.nlm.nih.gov/articles/PMC8537092/

      Edy's and Dreyer's ice cream

      There is a 10 year old post in this forum on Edy's and Dreyer's ice cream. The information is somewhat outdated and the thread is closed to further comment, so here is a new one. Edy's And Dreyer's Grand Vanilla Bean Ice Cream - 1.5 Quart is labeled "Gluten Free". This is a different answer than years gone by. I don't know the answer for any other flavor at this moment. On 1 May, 2026, Edy's website says: "As a general rule, the gluten in Edy's and Dreyer's® frozen dessert products is present only in the added bakery products, such as cookies, cake or brownies. We always label the eight major food allergens on our package by their common name. We recommend to always check the label for the most current information before purchasing and/or consuming a product. The exception to this rule is our Slow Churned French Silk frozen dairy dessert, which contains gluten in the natural flavors." https://www.icecream.com/us/en/brands/edys-and-dreyers/faq It seems that Edy's and Dreyer's are more celiac-friendly than they were 10 years ago. Once I found enough information to make today's buying decision, I stopped researching.

      probably not your situation @Mimiof2, but allow me to add one more to @trents list of celiac-mimics: "olmesartan-induced sprue-like enteropathy"

      Terrible Neurological Symptoms

      By knitty kitty · Posted

      My dad had an Abdominal Aortic Aneurysm.  Fortunately, it was discovered during an exam.  The doctor could feel my dad's heart beating in his stomach/abdomen.  The aneurysm burst when the doctor first touched it in surgery.  Since he was already hooked up to the bypass machine, my dad survived ten more years.  Close call! Triple A's can press on the nerves in the spinal cord causing leg pain.  I'm wondering if bowing the head might have increased the pressure on an aneurysm and then the nerves.   https://gulfcoastsurgeons.com/understanding-abdominal-aortic-aneurysm-symptoms-and-causes/ Abdominal Aortic Aneurysm Presenting as a Claudication https://pmc.ncbi.nlm.nih.gov/articles/PMC4040638/
