What Should I Do If The Test Result Is Negative
A negative test result indicates that it is very unlikely that you have coeliac disease. However, as no test is 100% effective and it is known that very low antibody levels the test may give a false negative result, we recommend that you consult your doctor if you have worrying gastrointestinal symptoms or the test result is contrary to your expectations.

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.

Understanding Wheat Allergy Vs Celiac Disease
Wheat is the most common of the grain allergies and affects about 0.4% of children. That is high enough to make it a top 8 food allergy. Wheat allergy is almost always an immune reaction to the gluten protein in wheat.
Wheat allergy, like cows milk allergy, can involve IgE antibodies and/or other immune cells. Celiac disease, on the other hand, is a non-IgE immune reaction that leads to severe inflammation of the small intestine.
Most people with celiac will react to wheat, barley, and rye. An IgE allergy to wheat is just to wheat, though people can also have IgE allergies to other grains.
Non-IgE allergy to wheat can also cause allergic eczema, EoE, FPIES, or other conditions just like milk allergy can.
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

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.

How Many Forms Of Gluten Intolerance Exist
This surprises some people , but there is more to gluten intolerance than celiac disease. While it is still considered the most serious medical condition among them, celiac disease is only one of several significant medical conditions triggered by the consumption of this troublesome protein composite.
- Celiac Disease
- Dermatitis Herpetiformis
- Gluten Ataxia
Along with gluten ataxia, a growing number of gluten-sensitive idiopathic neuropathies are being diagnosed. Collectively medical researchers now refer to these conditions as gluten-related disorders.
Unfortunately, each of these conditions require a different means for diagnosis and with two of them, NCGS and gluten ataxia, doctors and researchers havent yet agreed upon a consistent and accurate way to perform diagnosis.
In addition, one form of gluten intolerance, dermatitis herpetiformis, requires a skin biopsy, not blood work. Also, doctors and researchers havent yet agreed on how to identify a non-celiac gluten sensitivity in a consistent and accurate manner, other than to rely on a diagnosis by deduction.
In other words, if a gluten challenge reveals a problem with gluten but the patient tests negative for both celiac disease and a wheat allergy, then the patient will be diagnosed as non-celiac gluten sensitive .
Glutencheck Gluten Intolerance Test By Nanorepro
This is an at-home test for celiac disease that looks for antibodies related to the condition.
To take the test, a person needs to provide a blood sample via a finger prick. Next, a person mixes their sample with a solution and compares the color of the mixture with the shades on a color chart. Any changes in the color of the sample mixture can indicate that a reaction has occurred.
Unlike other tests, the GlutenCHECK test does not require a person to return their sample to a lab.

Symptoms Of Celiac Disease
Although digestive issues are common in children with celiac disease, most adults do not experience these symptoms. Instead, the following signs are often a red flag for celiac disease in adults:
- Amenorrhea
- Liver and biliary tract disorders
- Osteoporosis or osteopenia
- Peripheral neuropathy
- Seizures or migraines
- Unexplained iron-deficiency anemia
Whether or not you are experiencing any of these symptoms, it is crucial to undergo celiac disease testing if you have a first-degree relative with the condition, as this puts you at a one in ten risk of developing celiac yourself.
However, if you suspect that you have gluten intolerance rather than celiac, the single best way gluten intolerance test is to remove it from your diet, note how you feel without it, and how you feel when you add it back in.
Diagnostic Tests For Celiac Disease
If you experience digestive symptoms or signs of poor vitamin and nutrient absorption, such as unexplained weight loss, an NYU Langone gastroenterologist can perform diagnostic tests to determine whether celiac disease may be the cause. For adults, doctors typically recommend both blood tests and biopsies, in which tissue samples are examined under a microscope, to confirm the diagnosis.

Gluten Allergy Test Cost Without Insurance
Normally, the gluten allergy test providers mentioned above do not accept insurance. You are required to pay out of your pocket. Though the insurance is not covered, the gluten allergy test cost offered by the above providers is the lowest. You can contact our above service providers for more information.
Testing For Wheat Allergy
In babies who are showing symptoms of a wheat allergy, blood, or specific IgE testing for wheat can help identify if the allergy is real and if it is IgE-mediated. Many doctors will also test for other grain allergies at the same time.
Wheat allergy testing is less reliable than other foods because wheat proteins are similar to grass pollens. The only true test is an oral food challenge.

Diagnosing Celiac Disease & Gluten Sensitivity In Adults
NYU Langone gastroenterologistsdoctors that specialize in diseases of the digestive systemare experts in diagnosing celiac disease and gluten sensitivity. Celiac disease is an autoimmune disorder in which the immune system mistakenly attacks the digestive tract after a person consumes gluten, a protein found in wheat, rye, barley, and other foods and beverages. Some vitamins, medications, and personal care products such as lip balm contain gluten.
During digestion, food passes through the intestines, where nutrients are absorbed into the body. Most of this absorption occurs in the small intestine, where tiny finger-like projections along the small intestinal lining, called villi, sweep the nutrients from food into the bloodstream.
People with celiac disease, however, have a genetic susceptibility to recognize gluten differently. When someone with celiac disease eats food that contains gluten, it triggers the immune system to attack the small intestine. The body forms antibodies, or proteins, that attempt to remove gluten from the body as if it were a foreign invader. The antibodies also attack the lining of the small intestine, causing inflammation.
Over time, recurrent inflammation damages the villi in the small intestine, and the body doesnt absorb nutrients very well. This can lead to malnutrition and unwanted weight loss. The chronic inflammation also can cause abdominal discomfort.

Dna Test For Gluten Sensitivity
The answer lies in your DNA! There are two genes associated with gluten sensitivity: HLA-DQA1 and HLA-DQB1. The NIH estimates that somewhere between 30 and 40 percent of the US population carries one or both genes, but only 3 percent of carriers will actually develop celiac disease. To make things even more interesting: you can be a carrier for celiac disease or NCGS and not know it until an external event causes the gene to turn on. This is known as a trigger, and can be anything from being born , menopause, influenza, or even antibiotic use for a common infection . There are also countless environmental triggers known to trigger celiac disease such as exposure to certain chemicals
So, in a nutshell, there are three factors needed for you to experience celiac or NCGS: be a carrier for the gene, experience some sort of trigger to turn the gene on, and have a diet that contains gluten.
What Are The Risk Factors for Celiac Disease?
While celiac disease is rare, there are a few circumstances that would put you at an increased risk for the condition:
How Can I Find Out If I Have Celiac Disease or NCGS?
Symptoms And Causes Of Celiac Disease
People who have celiac disease commonly experience weight loss, as well as digestive symptoms, including diarrhea, abdominal pain, and bloating.
Some people notice mental and emotional symptoms, such as an inability to concentrate, commonly described as brain fog, or depression.
Not everyone with celiac disease experiences the same symptoms. Some people have no digestive complaints whatsoever, yet routine blood tests reveal low levels of vital nutrients, such as iron, vitamin B12, or vitamin D. NYU Langone doctors take all of these signs and symptoms into account when making a diagnosis.
The exact cause of celiac disease remains largely unknown. However, more than 99 percent of people with celiac disease test positive for two genetic variations known as HLADQ2 and HLADQ8. Not everyone who carries these variations develops celiac disease in fact, most people dont.
Some theories suggest environmental factors trigger celiac disease in people with these genetic variations, but more research is needed. Researchers have found that a family history of the disease increases a persons risk.

Is There A Gluten Intolerance Test
If you often feel bloated or get constipation and stomach pain after eating, you should first be examined by your doctor before cutting things out of your diet or deciding to go gluten-free.
If you get the medical all-clear and think certain foods could be contributing to your symptoms, it is worth considering a food intolerance test. Food intolerance is characterised as a delayed onset food reaction and is estimated to affect 45% of the UK population.
Understanding your personal food and drink intolerances, or food fingerprint, can help you identify what your body is reacting to. A YorkTest Premium Food Intolerance Test can pinpoint precisely which foods are causing elevated levels of IgG antibodies in your blood, as it tests reactions to more than 200 ingredients and shows your degree of reaction through a traffic light system.
It is also important to get expert nutritional advice, so you can replace your trigger foods with balanced alternatives and maintain a healthy diet.
