Allergy Test Neg To Wheat

[misgiss]

At 9 mos our son tested positive to wheat (prick test). After about a year we tried again and no hives so we thought he was okay. We just had him re-tested (blood test) (he is now 3 yrs) and it came back negative. We are still waiting for some other test results but could he test neg to wheat and still have celiac disease? In my mind that's kind of what celiac disease is, and allergy. I'm very new at this so please correct me if I'm wrong.

Another question, I noticed a lot of people on here are corn free or corn intolerrant. What is it with corn? Isn't it a veggie?

TIA

yes----you can test negative to wheat and still have celiac disease. celiac disease is not an allergy, it is a genetic, autoimmune disease. what test results are you waiting on?

You listed the second test as a blood test....what it an IgA or IgG type test? Because, if so, if he was not eating gluten-filled foods, then a gluten antibody test would be negative......and my first test (through Lame Advertisement dot com) didn't list wheat, but it did list gluten and gliadin, so perhaps that is the difference? Not sure.....and about the corn, you can be intolerant to ANYTHING, and after damaging the gut by eating gluten-filled foods when you are unaware of the problems that it is causing, many people develope problems with casien (milk/cheese), corn, soy, and other things. It is pretty common in Celiacs to have atleast one other "allergy" food.

Yes, you can have celiac disease and test negative to wheat as an allergen. I sure did! And no, corn is not a veggie, it's a grain.

You know, I'm still not as clear as I would like to be on the differences between intolerances, allergies, and celiac. I read a peice or two, and whilst I pick many things up quickly, this hasn't been one of them. Can anyone give or point me to a good break down of the differences?

I have read otherwise, can you explain?

I know that allergies involve allergens and antibodies. Your body creates antibodies (like histamine) to allergens. Other than that, I cant help. I tell people at resteraunts that I am allergic to gluten, because I think "intolerant" sounds like I don't like it (breat, croutons, etc). But I don't know the defining differences.

As Chrissy said--Celiac is not a typical wheat "allergy"...so a skin prick test will not tell you if he has Celiac or not. What other tests are you waiting on now?

Grey--

Info on difference below I have posted before. Hopefully this will help shed some light: (I will add that although a food intolerance doesn't involve the immune system like a typical IgE allergy does--it can affect it in some form. In the case of leaky gut--food proteins that should remain in the gut get out into the blood stream and the bodies produces antibodies to them--which is how you can have an IgG food intolerance test done.)

. What is the difference between food allergy and food intolerance?

Many people think the terms food allergy and food intolerance mean the same thing; however, they do not. A food intolerance is an adverse food-induced reaction that does not involve the immune system primarily.

A food allergy occurs when the immune system reacts to a certain food. The most common form of an immune system reaction occurs when the body creates immunoglobulin E (IgE) antibodies to the food. When these IgE antibodies react with the food, histamine and other chemicals (called mediators) cause hives, asthma, or other symptoms of an allergic reaction. Open Original Shared Link

Introduction

Foods can cause a number of reactions, not all of which are allergic. Anyone can experience an adverse reaction to a food. The types of adverse reactions are as follows:

Adverse Reactions to Foods

Food Intolerance - where the immune system is not involved in the reaction

* Food poisoning

* Idiosyncratic reactions to food

* Anaphylactoid reactions (they act like anaphylaxis but there is no allergy-IgE antibody involved)

* Pharmacologic reactions

Food Allergy - when the immune system is involved in the reaction

* IgE mediated (classic allergy- tests are available) Non-IgE mediated

* Type III immune response- a serum sickness like reaction

* Type IV immune response- a contact dermatitis type reaction

Food Allergy- Facts and Figures

Food intolerance accounts for 80% of all adverse reactions to food.

Food allergy accounts for 20% of all adverse reactions to food.

Allergic reactions can be itching, swelling, rash, spreading hives, vomiting, diarrhea, breathing difficulties and in the most severe of the allergic disorders, anaphylaxis can lead to collapse and death. By definition, anaphylaxis is an allergic reaction which involves two of the body's systems (eg respiratory and gastrointestinal or skin). Anaphylactic deaths as a result of insect bites or penicillin are usually very quick - within minutes - and due to cardiac arrest, anaphylactic deaths due to food allergies are usually due to suffocation (breathing difficulties).

Food intolerance reactions can be the same as above, as well as:

skin (rashes, swelling)

airways (asthma, stuffy or runny nose, frequent colds and infections)

gastrointestinal tract (irritable bowel symptoms, colic, bloating, diarrhea, vomiting, frequent mouth ulcers, reflux, bedwetting, 'sneaky poos', 'sticky poos')

central nervous system (migraines, headaches, anxiety, depression, lethargy, impairment of memory and concentration, panic attacks, irritability, restlessness, inattention, sleep disturbance, restless legs, moodswings, PMT).

Symptoms of food intolerance can come and go and change throughout life.
