Diagnosis and tests of gluten intoletence
Because of the wide variety of symptoms and its similarity to that of other diseases, it is a bit difficult to detect gluten intolerance. However, doctors have found out several effective ways of diagnosing celiac disease.
The human body contains certain auto antibodies which are concerned with reacting against the tissues or cells of the body. In gluten-intolerant people, the level of auto antibodies is higher than normal. It can be detected by several blood tests that include antigliadin antibodies, anti-tissue transglutaminase antibodies and anti-endomysium antibodies. It is important to eat food items that have a liberal dose of gluten before the test so that it can be detected properly whether you are intolerant to it.
This is done through the process of EGD or esophagogastroduodenoscopy. In it, a long endoscope is inserted into the duodenum through your mouth. Then, the doctor passes a flexible and long biopsy instrument through a small opening in the endoscope. This is done for the purpose of obtaining intestinal lining samples of the duodenum. The doctor might obtain multiple samples in order to ensure accuracy. This process is considered to be the most flawless method of determining gluten intolerance.
This is especially meant for people who have a family history of gluten intolerance but do not experience any of its symptoms. In this process, blood test is conducted in order to determine the presence of auto antibodies in the body along with its level.
It primarily refers to a skin rash that is intensely itchy and occurs on the knees, buttocks and elbows. If you have Dermatitis Herpetiformis, you won’t have any of the digestive symptoms usually associated with celiac disease or gluten intolerance. A skin biopsy or blood test can detect DH. If it is found out in the skin biopsy that you indeed have DH, it obviously points towards gluten intolerance.
