What this test screens for
Understanding the Celiac Disease Panel
The Celiac Disease Panel is a blood antibody test that screens for an immune response to gluten — the protein found in wheat, barley, and rye. The standard panel includes tissue transglutaminase IgA (tTG-IgA), the most sensitive and specific marker for celiac disease, plus total serum IgA to rule out IgA deficiency, which can produce a false-negative tTG-IgA result.
At our Ashburn lab, the Celiac Disease Panel is $179 and requires no doctor referral. An important requirement: you must be consuming gluten at the time of testing. Going gluten-free before the blood test — even for a few weeks — can suppress antibody levels and cause a false-negative result. Do not start a gluten-free diet before testing if celiac disease is a possibility.
A positive tTG-IgA result is not a diagnosis of celiac disease on its own — confirmation typically requires an intestinal biopsy during endoscopy, ordered by a gastroenterology provider. The blood panel is the standard first step. If the panel is negative but symptoms are strong, discuss non-celiac gluten sensitivity (NCGS) and additional testing with a gastroenterology provider.
Why people get this test
- Investigating chronic digestive symptoms (bloating, diarrhea, abdominal pain, gas)
- Investigating unexplained anemia, fatigue, or nutritional deficiencies
- Family history of celiac disease (first-degree relatives have roughly 10% lifetime risk)
- Screening due to associated conditions (type 1 diabetes, Down syndrome, autoimmune thyroid disease)
- Investigating skin rash consistent with dermatitis herpetiformis
- Before starting a long-term gluten-free diet to confirm whether celiac disease is the cause
What to expect
From check-in to results — what your visit looks like
Most visits take under 15 minutes. Here’s the full arc, start to finish.
How to prepare
You must continue eating gluten-containing foods (bread, pasta, crackers, cereal) for at least 6 weeks before the test for reliable results. Going gluten-free before testing can suppress antibody levels and produce a false-negative. No fasting required. Take morning medications normally.
During your visit
A single small blood draw — typically two tubes — completed in about 5 minutes. Most visits are 10 to 15 minutes total from check-in to walking out.
Getting your results
Results post to your secure online portal within 3 to 5 business days. The report includes tTG-IgA with the lab’s reference range and total serum IgA. A positive or borderline tTG-IgA result should be reviewed with a primary-care or gastroenterology provider — confirmation typically requires a small intestinal biopsy. We can fax the results to any provider you name.
Confidential
Your results never go through your insurance carrier.
Transparent
Price you see is price you pay.
Fast
Most results in 24–72 hours through our portal.
Doctor’s order
Included as part of every visit. No referral needed.
FAQ
Celiac Disease Panel — what people ask
Specific questions about the celiac disease panel. For anything not covered, call 571-500-7030.
Why do I need to keep eating gluten before the test?
The tTG-IgA antibody is produced in response to gluten exposure. If you have already eliminated gluten from your diet, the immune response decreases and antibody levels may fall below the detectable range — producing a false-negative result. Reliable testing requires active gluten consumption for at least 6 weeks beforehand.
What if the panel is negative but I still feel bad after eating gluten?
A negative celiac panel with ongoing symptoms may indicate non-celiac gluten sensitivity (NCGS), wheat allergy, or another gastrointestinal condition such as IBS. NCGS is not detected by the tTG-IgA test and is typically diagnosed by a gastroenterology provider after celiac disease and wheat allergy have been ruled out.
Does a positive blood test confirm celiac disease?
A positive tTG-IgA result is a strong indicator but not a standalone diagnosis. Most gastroenterology guidelines recommend confirming with a small intestinal biopsy obtained during upper endoscopy — this allows the provider to assess villous atrophy, the intestinal damage characteristic of celiac disease. Discuss next steps with a gastroenterology provider.
