Why This Test Matters for Gluten Sensitivity

Gluten sensitivity can cause symptoms like stomach pain, bloating, or digestive issues, even if you don’t have celiac disease. This test checks for antibodies that signal your immune system is reacting to gluten, which may not cause damage but still affects digestion or overall health.

What to Expect Before the Test

No special preparation is needed. You’ll provide a blood sample, usually drawn from your arm. If you’re on a gluten-free diet, your doctor may ask to confirm your diet before testing to avoid false results.

What the Results Mean

Positive results for certain antibodies may indicate gluten sensitivity or celiac disease, but they don’t confirm a diagnosis alone. Your doctor will review your symptoms, medical history, and possibly other tests to make a full assessment.

Common Symptoms Linked to Gluten Sensitivity

Symptoms may include digestive issues (like diarrhea or bloating), fatigue, joint pain, or skin rashes. Some people experience mild symptoms, while others may have severe reactions.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This test is often used alongside other blood tests (like endoscopy or genetic testing) to diagnose celiac disease or gluten sensitivity. If positive, it may guide dietary changes or referrals to a specialist for further evaluation.

Frequently asked questions

What triggers this test?
Your doctor may order this test if you have symptoms like persistent digestive issues, unexplained fatigue, or a family history of celiac disease or gluten sensitivity.
How long does it take to get results?
Results are typically available within 1–3 business days, depending on your lab’s processing time.
Can I eat gluten before the test?
