Celiac Disease is an autoimmune disorder in which the body produces autoantibodies, Immunoglobulin A or Immunoglobulin G, which attack gluten that a person with Celiac Disease eats. Gluten is a protein found in many foods including Wheat, and in dietary proteins found in Rye and Barley.
If a person with Celiac Disease eliminates foods and products containing gluten from their diet, autoantibody levels should fall. If the levels don’t fall it is possible that the person has a form of the disease that doesn’t respond to gluten elimination or there are hidden sources of gluten still in the diet. These can be in unsuspected foods and products such as salad dressings, cough syrup or even the adhesive on an envelope. Some people are extremely sensitive to gluten and will need to remove all sources of it from their diet.
WHY DO I NEED TO BE TESTED FOR CELIAC DISEASE?
Are you experiencing consistent diarrhea, abdominal pain, anemia, fatigue, weakness or weight loss?
These symptoms could be a sign of Celiac Disease. Because those with Celiac Disease may have difficulty absorbing enough nutrients from their food, malnutrition can become severe. Unfortunately, the symptoms are frequently nonspecific and may change over time making this disease difficult to identify and diagnose. Sometimes, the symptoms are mild and then may become severe or they may vary significantly over time. This test can help to differentiate between Celiac Disease and other inflammatory bowel diseases.
Celiac Disease is relatively common; about 1 in every 100 to 150 people are affected, but most of them are not aware of it because the symptoms are so variable. Although many people have discovered Gluten-Free diets as a way to eat healthier or to try to lose weight, it is critical that those with Celiac Disease avoid gluten completely or they may experience long term health issues. Children could experience delayed development, short stature and failure to thrive. Adults may experience severe intestinal damage over the long term.
The test should be done when the person has been ingesting gluten products for several weeks prior to the test. In order to test for the autoantibodies it is necessary that there is still gluten in the body. If the test is being used for monitoring of the effectiveness of a gluten-free diet no such preparation is necessary. Test results are either positive or negative for Celiac Disease.
