About this test

Everything you need to know about Coeliac Antibody

In coeliac disease, gluten — found in wheat, barley and rye — triggers an immune reaction that damages the lining of the small intestine. Symptoms vary widely: bloating, diarrhoea or constipation and tummy pain, but also tiredness, iron-deficiency anaemia, mouth ulcers, weight loss or no obvious symptoms at all. Many people go years without a diagnosis.

This blood test looks for the antibodies the body makes in coeliac disease. The IgA antibody is the main test; an IgG antibody is included because some people naturally make very little IgA, which can hide a positive result. A positive result is not a diagnosis on its own — it usually leads to a referral for confirmation — so please keep eating gluten until that has been decided.

  • Bloating, diarrhoea, tummy pain or wind that keeps coming back

Frequently Asked

Coeliac Antibody — FAQs

Do I need to be eating gluten?
Yes — this is the most important thing. The antibodies are only made while you are eating gluten, so have it in more than one meal every day for at least 6 weeks before you collect your sample. If you have already cut it out, talk to us before ordering.
What happens if my result is positive?
Our clinician explains the result and recommends seeing your GP, who will usually refer you to a gastroenterologist to confirm the diagnosis, often with a biopsy of the small intestine. Keep eating gluten until you have been told it is safe to stop.
How is this different from the genetic Coeliac Disease Test?
The genetic test, taken at the clinic, shows whether you carry the genes that make coeliac disease possible — useful for ruling it out. This antibody test shows whether the immune reaction is happening now.
Is this a test for gluten intolerance?
No. It looks specifically for coeliac disease, an autoimmune condition. Non-coeliac gluten sensitivity does not have a blood test.
How does the kit reach me?
We post it to your address anywhere in the UK as soon as your order is paid, and email you when it has been dispatched. Delivery is free on every home blood test kit. Everything you need to collect your sample and send it back is in the box.
How do I collect the sample?
Your kit contains everything you need and step-by-step instructions. Read them through first, collect at the time of day this test needs (see the preparation note above), label the sample and pack it in the return packaging provided.
When should I post my sample back?
On the day you collect it, Monday to Thursday, and not the day before a bank holiday — so it reaches the laboratory quickly and does not sit in the post over a weekend. A sample that arrives too old may not be able to be analysed.
Can I order several kits at once?
Yes. Use “Add to order” on each kit and then “Order” in the bar at the bottom — they go into one order and one payment and are posted together. Clinic blood tests are booked separately, because they need an appointment rather than an address.
How do I pay?
Home kit orders are paid by bank transfer. When you place your order we show our bank details and your payment reference on screen and by email, and we post your kit as soon as the payment reaches us.
How do I get my results?
Once the laboratory has analysed your sample, your results are released to your secure account with a written explanation from our clinical team, and a call where something needs talking through. Turnaround depends on the test and starts when the laboratory receives your sample.
