Celiac Disease Screening Test

Celiac disease is an autoimmune and digestive disorder. When you have celiac disease, your immune system attacks your small intestine whenever you eat foods containing gluten (a protein found in wheat, rye, barley, and triticale) because it mistakes gluten as a threat to your body. This damages the small intestine and prevents you from getting the nutrients you need from food.

This test may be right for you if you are having symptoms when eating foods that contain gluten (wheat, barley, rye, triticale), such as:

• Abdominal pain

• Abdominal bloating

• Constipation or diarrhea

• Excessive gas

• Nausea or vomiting

• Unexpected weight loss

This test may not be right for you if:

• You have already been diagnosed with celiac disease

• You are not currently eating a gluten-containing diet or have not eaten gluten-containing foods in the last three months. (Though you should talk to your healthcare provider for guidance before adding gluten back into your diet for testing!)

• Have known IgA deficiency 

If you have any serious symptoms, please seek medical attention right away.

You may be at increased risk for celiac disease if you:

• Have a family member with celiac disease

• Have other autoimmune disorders

• Have Type 1 diabetes

While we can't speak to other tests specifically, we can say that the Celiac Disease Screening Test follows a clinically-accepted testing algorithm that measures tTG-IgA and total IgA.

The instruments and methods used by our laboratories are similar—and often exactly the same—as those used by a doctor's office. Our at-home sample collection methods, like dried blood spot and saliva, have been widely used for decades.
