Celiac Disease Vs Non

Testing For Gluten Sensitivity

The first and most serious condition related to gluten is a condition known as Celiac disease .

Celiac disease is a condition which your body creates antibodies to gluten particles.

Upon consumption of gluten, your body reacts to various portions of the gluten molecule which results in immune-mediated damage to the intestinal tract .

Damage to the intestinal tract results in blunting of the intestinal villi which may result in malabsorption of both nutrients and calories leading to many different problems.

This damage may also cause increased intestinal permeability and allow the absorption of pathogens and particles that would otherwise not have been absorbed.

This mechanism is what many believe may be the link between the development of further autoimmune diseases and Celiac disease and is known as molecular mimicry .

Celiac disease results in symptoms in both the intestinal tract and outside of the intestinal tract.

The diagnosis of Celiac disease is made by assessing serum levels of certain antibodies, the presence of which may indicate the disease state in your body .

You can see an example of a positive test below:

The “gold standard” for diagnosis of Celiac disease is an intestinal biopsy which shows immune-mediated damage and intestinal damage.

In most cases, this is NOT necessary as the presence of positive antibodies in the serum should be enough to make the recommendation to alter your diet.

This is where things can be confusing .

The main question is this:

Gluten And Health Benefits

Gluten is most often associated with wheat and wheat-containing foods that are abundant in our food supply. Negative media attention on wheat and gluten has caused some people to doubt its place in a healthful diet. There is little published research to support these claims in fact published research suggests the opposite.

In a 2017 study of over 100,000 participants without celiac disease, researchers found no association between long-term dietary gluten consumption and heart disease risk. In fact, the findings also suggested that non-celiac individuals who avoid gluten may increase their risk of heart disease, due to the potential for reduced consumption of whole grains.

  • Many studies have linked whole grain consumption with improved health outcomes. For example, groups with the highest intakes of whole grains including wheat compared with groups eating the lowest amounts were found to have significantly lower rates of heart disease and stroke, development of type 2 diabetes, and deaths from all causes.

Gluten may also act as a prebiotic, feeding the good bacteria in our bodies. Arabinoxylan oligosaccharide is a prebiotic carbohydrate derived from wheat bran that has been shown to stimulate the activity of bifidobacteria in the colon. These bacteria are normally found in a healthy human gut. Changes in their amount or activity have been associated with gastrointestinal diseases including inflammatory bowel disease, colorectal cancer, and irritable bowel syndrome.

Testing Treating And The Gluten

When someone who has dermatitis herpetiformis consumes gluten, his or her immune system launches an attack by producing antibodies. In celiac disease, the immune system attack damages the absorbing lining of the small intestine. In DH, the attack primarily takes place in the skin as antibodies stimulated in the intestine circulate through the bloodstream.

Immunoglobulin A is deposited in the skin, triggering an immune reaction that results in the formation of the lesions.

Whats interesting in DH is that these immune cells, once armed, leave the battlefield and go to the skin.

Although the effect is seen on the skin, touching gluten-containing foods or lotions, creams and other body products has not been shown to trigger a DH rash.

Those who have DH dont always have classic intestinal damage, but the condition is still considered full-blown celiac disease, Fasano says, noting that in 25 percent of DH cases only the skin is affected. The remaining 75 percent have damage to the villi that line the intestine, but this is generally limited and patients may have no obvious gastrointestinal symptoms.

DH is diagnosed through the anti-tissue transglutaminase antibody blood test and a skin biopsy. When the biopsy is done, a sample is taken from the area next to a skin lesion to determine if IgA occurs in deposits that appear in a granular pattern. When DH is diagnosed this way, the intestinal biopsy used to diagnose celiac disease is not needed.

What Are The Symptoms Of Coeliac Disease

People with coeliac disease can have severe symptoms, or they may have no obvious symptoms at all. Common symptoms include:

Many of these symptoms are very common and can occur in other conditions such as wheat intolerance, non-coeliac gluten sensitivity or irritable bowel syndrome. However, coeliac disease is widely recognised as being under-diagnosed so its important to consider it as a possible cause for a few or many of these symptoms.

Its important not to self-diagnose coeliac disease if you feel better when you remove gluten from your diet. Coeliac disease is an important cause of gluten intolerance, yet feeling better if you dont eat gluten doesnt mean you have the condition there could be other causes of your symptoms.

Even if you have no obvious symptoms, there may still be damage to your bowel.

Its important to be screened for coeliac disease if you have:

  • an autoimmune disease such as type 1 diabetes or an autoimmune thyroid condition

Dermatitis Herpetiformis Rash Symptoms

Gluten Sensitivity Intolerance Self Test

Although dermatitis herpetiformis can form anywhere on your body, its most frequent locations include the elbows, knees, buttocks, lower back and the back of the neck. In most cases , its one of the itchiest skin conditions you can experience.

This photo shows a close-up of the rash, with its distinctive tiny reddish-purple bumps. The dermatitis herpetiformis bumps usually take several days to heal , and once healed, those bumps will leave behind small purple marks that last for weeks or months.

People with long-standing dermatitis herpetiformis usually have continuously reddened, purple-dotted skin where their rash occurs.

When dermatitis herpetiformis is severe, the lesions often are topped with clear, fluid-filled blisters that pop easily when scratched . The liquid in those blisters contains white blood cells, which are drawn to the area as a result of the autoimmune attack on the skin.

There Are Many Symptoms Of Gluten Intolerance And Celiac Disease

Most people wonder if they have celiac disease or a gluten intolerance because of gastrointestinal symptoms like gassiness, diarrhea, constipation or excessive bloating. But other symptoms might not be so obvious. And while gluten intolerance and celiac disease are different, many of the symptoms can be similar. Here are some signs of celiac disease and gluten intolerance you might not be aware of.

  • Digestive issues
  • Tingling or numbness in hands and/or feet
  • Bone and joint pain

How Long Does It Take To Cleanse Your Body Of Gluten

This varies from person to person. Some people start feeling better after just a few days of eliminating gluten in their diet. For others, symptoms of gluten intolerance dont go away for a few weeks or more. In some cases, certain symptoms might disappear early while others might take longer to go away.

A Final Word About A Gluten Free Diet

A gluten free diet can present a challenge in regards to whole grain intake since it eliminates some of the most common sources of whole grain, including wheat, rye and barley. Fortunately, it can also provide an opportunity to eat a more whole food diet as is evidenced by the list above. While there are many refined gluten-free grain replacements such as cornstarch, potato starch, tapioca starch and white rice flour, the variety of nutritious gluten free whole grains is plentiful. So, rather than having the gluten free diet be a challenge, look at is as an opportunity to increase both variety and nutrient content through the incorporation of the above mentioned gluten free foods, including whole grains.

Id like to leave you with two gluten free recipes to try that will help incorporate the whole grains listed above.

Blood Panels That Might Suggest A Problem

The following tests are often conducted by thorough doctors when evaluating patients for a non-celiac gluten sensitivity, a gluten intolerance or a verified case of celiac disease:

  • Stool Fat test, to determine malabsorption level .
  • Complete Blood count , to determine anemia.
  • Erythrocyte Sedimentation Rate to look for inflammation.
  • C-Reactive Protein to further watch for chronic inflammation.
  • Vitamins A, D, E and K to check for vitamin deficiency relating to malabsorption in the proximal small intestine.
  • Comprehensive Metabolic Panel to analyze protein, calcium and electrolyte levels as well as to check liver and kidney functions.

Ive also had readers inform me that theyve had doctors test and confirm a Non-Celiac Gluten Sensitivity with the gliadin IgG non-deamidated antibody test. I think many doctors and researchers would consider this too simple and narrow, but at least some anecdotal evidence suggests otherwise.

How To Tell If You Have A Gluten Intolerance

After experiencing the common symptoms of gluten intolerance, many people try keeping a food diary or cutting out certain foods themselves, but it can be hard to ascertain for sure what the culprits are. Moreover, a diet suitable for one person may not help another, as every individual has their own food triggers.

However, since symptoms may not show for up to three days after eating problem ingredients and, on average, people react to between four and six ingredients, it is sometimes difficult to work out what specifically is causing a reaction.

Risk Factors Of Gluten Allergy

Gluten intolerance can develop in anyone. It is more commonly seen in white people and females. It runs down the family, people with a heredity history of gluten allergies, and children are at a higher risk of developing the allergy. Also, a person with a parent or sibling who has this gluten allergy has a 1 in 10 chance of developing it, too.

Allergy Test Cost With Insurance

Gluten Intolerance Symptoms &  Treatment Methods

Insurance companies in the U.S. cover allergy testing costs including gluten allergy testing. But, our allergy testing providers do not accept any health insurance. In the case of your insurance company assuring for reimbursement, our providers can give you the receipt containing all the details needed for reimbursement purposes.

It is recommended to check with your insurance company regarding the reimbursement if you get tested with the above service providers.

How Common Is Soy Allergy In Infants

Who can develop MSPI? Any baby can develop intolerance to cows milk and/or soy proteins. It does not matter if the baby is breastfed or formula-fed. As many as 2-7% of babies under one year of age have intolerance to cows milk, and in our area, 60% of those babies will also develop intolerance to soy proteins.

Genetic Testing For Celiac Disease

The most established genetic test is specific to celiac disease and not necessarily for a wheat allergy, a non-celiac gluten sensitivity or a broader intolerance. But it can help either verify the presence of celiac disease or identify people who may be predisposed to developing celiac disease. Because it can be done in a non-invasive manner , this celiac disease genetic test is often done for at-risk children.

The test looks for the HLA-DQ2 and HLA-DQ8 genes. If one or both genes are present and the patient has a family history of digestive concerns, the individual is at a greater risk of developing celiac disease at some point in his or her life.

Please note, however, that it is still possible to have these genes and not develop celiac disease. In fact, around 35% of the general population has these genes while around 1% of the population has celiac disease. That means millions of people have the so-called celiac gene but do not have celiac disease.

So this test is usually either to take preliminary steps in identifying and helping at-risk individuals or to help confirm a diagnosis begun with some of the tests listed earlier in this lesson.

Diarrhea Constipation And Smelly Feces

Individuals with celiac disease experience inflammation in the small intestine after eating gluten.

This damages the gut lining and leads to poor nutrient absorption, resulting in significant digestive discomfort and frequent diarrhea or constipation (

That suggests that gluten exposure on its own may induce feelings of depression, irrespective to digestive symptoms.

Clinical Gluten Intolerance Tests

The BEST Test for Gluten Sensitivity

In the case of celiac disease, we now have 4 different established blood tests to help identify it:

  • Deamidated Gliadin Peptides
  • IgA and IgG Antigliadin Antibodies
  • IgA Endomysial Antibodies
  • tgG Tissue Transglutaminase Antibodies

In addition, the following test is almost always ordered to identify patients whose test results will be skewed due to an IgA deficiency:

Total IgA antibodies

None of these are 100% specific or 100% sensitive, which is why a doctor experienced in diagnosing celiac disease and a non-celiac gluten sensitivity will order several of these tests.

Since none of these can give you a 100% accurate answer, your doctor will consider your lab results and determine if you need an endoscopy with biopsy. Doctors often use more than the lab results to make this decision: your symptoms, medical history and family history are all taken into consideration.

An intestinal biopsy is considered, by most doctors and researchers, to be the only definitive test for celiac disease. It is often referred to as the gold standard for celiac disease diagnosis.

If your doctor decides to do a blood panel for celiac disease, try to make sure he or she uses the most recent and accurate tests: Deamidated Gliadin Peptides and IgA Endomysial Antibodies.

In addition, the Total IgA Antibody test should always be taken to determine if you are IgA deficient. If you are IgA deficient, they will need to read the results of your other tests differently .

Is The Test Result Correct

CoeliacScreen has been validated against laboratory tests and has been shown to be very reliable, , provided the instructions are followed carefully. The test can only give a false negative result in rare cases, such as when the levels of tTG antibodies are very low. Please note however that the test result can be adversely affected if insufficient blood is used or it is dispensed incorrectly.

The Key To Gluten Intolerance Testing

The key with these gluten intolerance test in the lab is you MUST be eating gluten for roughly 4 weeks prior to testing in order to detect gluten antibodies. That being said, if you know you dont tolerate gluten I do not recommend adding it back into your diet just to see what happens on a test.

If you are certain that gluten is to blame for your symptoms, I would avoid it no matter what any test says! In my experience, testing does not always have the most valid responses when compared to the gold standard of an elimination diet.

As I often told the patents in my clinic: Your body knows better than any test. If your symptoms disappear when you take gluten out of your diet and return when you add it back in even if you have a negative test result you still have an issue with gluten. So dont eat it

Us Food Intolerance Core Test

U.S. Food Intolerance offers several home tests for food sensitivities based on IgG measurements. Their basic test, the Core Test, can check for sensitivity to gluten and around 300 foods.

However, it is worth keeping in mind that no evidence indicates that food sensitivity tests based on IgG levels correlate with symptoms.

To take the test, a person needs to give a hair sample.

U.S. Food Intolerance says that results come back within 5 days of the lab receiving the sample. The report includes a complementary metals and nutritional deficiency test.

A Potential Problem With Gluten Intolerance Testing

How do you get tested for gluten allergies?

I want to mention that one potential problem with gluten intolerance testing is that gluten is made up of several hundred peptides and gliadin is made up of 12 different sub-fractions. Most modern-day gluten intolerance testing focuses on only the alpha-gliadin Therefore, there is considerable room for error and false-negative tests.

However, a lab called Cyrex Lab tests for these sub-fractions and may help to minimize false negatives in gluten intolerance testing. Cyrex also offers an Array 4 test to check for gluten cross-reactivity with other grains.

How Is Gluten Intolerance Diagnosed

Your healthcare provider carefully reviews your symptoms and medical history. If they suspect you have a gluten intolerance, these are the next steps to confirm the diagnosis:

  • Step 1: You eat a diet containing gluten for about six weeks. During this time, your healthcare provider performs blood tests and skin tests to rule out a wheat allergy or celiac disease. There isnt a gluten intolerance test.
  • Step 2: If you dont have a wheat allergy or celiac disease, your healthcare provider will ask you to exclude gluten from your diet for at least six weeks. Keep a thorough record of your symptoms during this time, noting which symptoms improve.
  • Step 3: If your symptoms do improve while youre on a gluten-free diet, you gradually reintroduce gluten back into your diet. If symptoms return, you likely have a gluten intolerance.
