What is the Labcorp test no. for a Celiac Disease Panel?

Labcorp test no. 164640. On a Labcorp requisition the test is printed as "t-Transglutaminase (tTG) IgA". If you are holding a doctor's order, that is the line to look for; a TestWell requisition carries the same code.

Can I walk into Labcorp for a Celiac Disease Panel without a doctor?

Yes, with a requisition. Labcorp patient service centers draw what a requisition orders; they do not write orders. You can get one from your doctor, buy the test on Labcorp OnDemand ($119.00), or order through TestWell ($124.99 + $6 fee), where a licensed physician in our network authorizes the order and the Labcorp requisition arrives by email, usually within minutes. New York and New Jersey do not allow self-ordered draws at Quest or Labcorp; TestWell orders from those states route to BioReference instead.

Do I need an appointment at Labcorp?

Most Labcorp patient service centers take walk-ins, and an appointment on Labcorp's site shortens the wait. Bring a photo ID and the emailed requisition (on your phone is fine). No fasting is required for this test. You must be eating gluten daily for at least 2–3 weeks before this test. Do not start a gluten-free diet before testing.

How long do Labcorp Celiac Disease Panel results take?

Results post to your TestWell portal in 3–7 business days after the draw, with reference ranges and the option to share them with your clinician. Labcorp runs the sample in its own CLIA-certified laboratory whichever way it was ordered, so the result and the turnaround are the same as a doctor-ordered Celiac Disease Panel.

Is a Celiac Disease Panel cheaper at Labcorp or Quest Diagnostics?

Through TestWell the price is the same $124.99 at either lab — pick the location that is convenient; the requisition is written for the lab you choose. On the labs' own sites, Labcorp OnDemand lists it at $119.00; Quest Health does not list this test for consumers, so there is no lab-direct price to compare on that side.
