Diagnosing Celiac Disease

The doctor will ask about your symptoms and medical history. A physical exam will be done. Symptoms are similar to those of other conditions. It may take a long time to get a diagnosis. Early diagnosis and treatment reduce the risk of complications.

Tests may include:

• Blood tests-to detect the presence of gluten antibodies (produced by the immune system) and look for evidence of malabsorption (anemia, vitamin and mineral deficiencies)
• Stool tests-to check for evidence of malabsorption
• Endoscopy-a thin, lighted tube inserted down the throat to examine the intestine
• Biopsy -removal of a small sample of tissue during endoscopy to test for inflammation and tissue damage
• Repeat biopsy-a biopsy performed several weeks after treatment begins to confirm the diagnosis
