Diagnosis of Celiac Disease

The doctor will ask about your symptoms and health history. A physical exam will be done. This may be enough to suspect celiac disease. Tests may be done to confirm the disease or rule out other health problems, such as an infection or food allergy.

Finding the disease early can lead to early treatment. This can slow or stop damage. Tests for celiac disease are:

Blood Tests

A blood test will be done to look for gluten antibodies. This is a sign that the body is reacting to gluten. This can confirm the diagnosis.

Celiac disease often runs in families. Genetic testing may be done to rule out the disease as a cause.


An upper GI endoscopy uses a scope that is passed down the throat. It lets the doctor look at the inside of the intestine.

Tools can also be passed through the scope to do a biopsy. A sample of the intestine will be removed and checked in a lab. This will show any damage and help confirm the diagnosis.
