Continued testing is encouraged to establish an accurate diagnosis, whether for celiac disease, non-celiac gluten sensitivity , or other diseases with similar symptoms. To confirm a celiac disease diagnosis, your doctor may recommend an upper gastrointestinal endoscopy. This procedure will allow your doctor to identify any inflammation or damage in your small intestines, which is a sure sign of celiac disease. Your doctor will take a small biopsy of your intestines during the endoscopy, which will help to confirm your diagnosis.
In order for the endoscopy to be accurate, the patient must be on a gluten-containing diet. An endoscopy may sound like a big procedure, but it only takes about 15 minutes and is a low-risk procedure.
Learn more about endoscopies for celiac testing. Currently, there are no accepted methods of testing for gluten sensitivity. Learn more about gluten sensitivity. Celiac disease damages the villi, which are finger-like projections in the small intestine.
Villi are responsible for absorbing nutrients from food. Because of this, it is highly likely that people with celiac disease will be deficient in essential vitamins and nutrients when diagnosed. Laboratory tests should be done within three to six months following a diagnosis and annually for the rest of your life. Learn more about follow-up testing for celiac disease. Without one of these genes, it is virtually impossible to develop celiac disease.
The celiac disease genes alone are not enough to develop celiac disease. Up to 40 percent of people have these genes, yet only a very small percentage of these people go on to develop it. This trigger can be a stressful event, illness, surgery, pregnancy, etc. Because having the genes does not automatically lead to celiac disease, genetic testing can only rule out celiac disease. It cannot concretely diagnose celiac disease. Genetic testing is beneficial for relatives of people diagnosed with celiac disease.
Since it is a genetic hereditary autoimmune disease, family members are also at risk for developing it. If the test is negative, it should be repeated every years or sooner if symptoms occur. Those with negative test results can go on to get the gene test. If the gene test is negative, the relative can stop with regular screening.

Your GP will take a blood sample and test it for antibodies usually present in the bloodstream of people with coeliac disease. You should include gluten in your diet when the blood test is carried out because avoiding it could lead to an inaccurate result. If coeliac disease antibodies are found in your blood, your GP will refer you for a biopsy of your gut. However, it's sometimes possible to have coeliac disease and not have these antibodies in your blood.
If you continue to have coeliac disease-like symptoms despite having a negative blood test, your GP may still recommend you have a biopsy. A biopsy is carried out in hospital, usually by a gastroenterologist a specialist in treating conditions of the stomach and intestines.
A biopsy can help confirm a diagnosis of coeliac disease. If you need to have a biopsy, an endoscope a thin, flexible tube with a light and camera at one end will be inserted into your mouth and gently passed down to your small intestine. Before the procedure, you'll be given a local anaesthetic to numb your throat and perhaps a sedative to help you relax.

Intestinal fatty acid binding protein I-FABP : When cellular damage occurs, this cytosolic protein is released into the systemic circulation of blood and could indicate unintentional gluten intake. Radiology: Some radiological findings may indicate the presence of celiac disease, e. If you are currently on a gluten-free diet, your physician may recommend a gluten challenge to allow antibodies to build in your bloodstream prior to testing.
NASPGHAN recommends eating roughly 2 servings of gluten, equivalent to 2 slices of wheat-based bread, daily for weeks prior to testing. The Celiac Disease Center at the University of Chicago recommends eating gluten every day, in an amount equivalent to at least 1 slice of bread, for at least 2 to 3 weeks prior to undergoing biopsy.
Please consult with your gastroenterologist regarding your gluten challenge. A gluten challenge should only be supervised by a physician trained in celiac disease, who can move you immediately to a biopsy if your symptoms are severe. A gluten challenge is not recommended before the age of 5 or during puberty. Since celiac disease is genetic, this means it runs in families. A negative gene test excludes the possibility of later developing celiac disease, so this can be valuable information for first-degree family members.
