You should receive the findings in roughly 1-2 weeks. The results will be discussed with you by your child's doctor. They may call you or come to see you in their office. There are several different types of tests that may be done to diagnose celiac disease. Some of these tests can also help doctors find out if your child is at risk for other diseases or problems. Not all tests are used in every case, so not all children will have all of their symptoms checked through laboratory studies. Tests that can show damage to the intestinal wall from gluten include: Biopsy - a small piece of tissue is taken from the intestine and examined under a microscope. This is the only way to know for sure if you or your child has celiac disease. A portion of a normal-looking piece of intestinal tissue shows signs of damage caused by gluten when stained with hematoxylin and eosin (H&E). Gluten antibody tests - these check for antibodies against gluten in the blood. Antibodies are proteins produced by the body in response to foreign substances such as viruses and bacteria but also including gluten.
