The problem
Half the coeliac tests we see are done wrong.
People stop gluten before the test, or the lab skips total IgA, or nobody explains what to do with a borderline result. It’s frustrating — and easily avoided.
-
Already gluten-free?
A negative test whilst you’re off gluten means almost nothing. We’ll walk you through a supervised gluten challenge or HLA-DQ2/DQ8 typing.
-
Borderline or equivocal?
We add EMA and DGP, check total IgA properly, and get a consultant gastroenterologist to interpret it.
-
Positive result?
We book upper endoscopy with duodenal biopsy for definitive diagnosis, and connect you with a dietitian.

What it shows
Who should get tested — and why.
Coeliac disease is common (roughly 1 in 100) and badly under-diagnosed. These are the situations where a proper test is worthwhile.
-
Coeliac symptoms
GI symptoms plus tiredness, weight change, brain fog or mouth ulcers — the classic and the atypical presentations.
-
Family history
A first-degree relative with coeliac increases your risk roughly ten-fold. Screening is worthwhile even without symptoms.
-
GI symptoms in general
Diarrhoea, bloating, abdominal pain or IBS-type symptoms that don’t settle — coeliac is a common missed diagnosis.
-
Unexplained iron deficiency
Iron-deficiency anaemia without an obvious cause is one of the most reliable triggers for coeliac testing.
-
Type 1 diabetes screening
People with type 1 diabetes have a much higher rate of coeliac disease and should be screened at diagnosis and periodically.
-
Dermatitis herpetiformis
The intensely itchy blistering rash that is, in effect, coeliac disease of the skin. Antibody testing is part of the work-up.
-
Autoimmune thyroid disease
Hashimoto’s and Graves’ commonly cluster with coeliac. Screening is reasonable in autoimmune thyroid patients.
-
Red flag: weight loss + malabsorption
Unintentional weight loss with steatorrhoea or malnutrition needs urgent gastroenterology review, not just a blood test.
Panels we arrange
The coeliac panels we arrange most.
What each option is actually for.
-
Anti-tTG + IgA
The correct first-line test — tissue transglutaminase IgA with total IgA to rule out IgA deficiency.
-
Full panel (tTG, EMA, DGP)
Adds endomysial antibodies and deamidated gliadin peptide for equivocal cases and IgA deficiency.
-
Coeliac panel + gastro consult
Panel plus a consultant gastroenterology appointment to interpret results and plan the next step.
-
HLA-DQ2/DQ8
Genetic typing — useful mainly to rule coeliac out, especially in people already on a gluten-free diet.
-
Panel + endoscopy + biopsy
The full diagnostic pathway. Upper endoscopy with duodenal biopsy remains the gold standard in adults.
-
Follow-up surveillance
Repeat antibody testing to confirm response to a strict gluten-free diet, usually at 6 and 12 months.
-
Paediatric coeliac work-up
Paediatrician-led pathway with age-appropriate serology and, where indicated, biopsy under a paediatric gastroenterologist.
-
Post-treatment gluten-challenge test
For people already gluten-free where the original diagnosis is in doubt — a supervised gluten reintroduction with retesting.

Preparation and practicalities
Prepare properly — or the test isn’t worth having.
Coeliac serology is simple, but only if you get the preparation right. Here’s what actually matters.
-
You MUST be eating gluten
You need to be eating gluten daily — at least two slices of wheat-based bread a day (or equivalent) — for at least six weeks before testing. Otherwise the test can be falsely negative.
-
IgA deficiency changes the test
About 1 in 40 people with coeliac are IgA deficient. If total IgA is low, we switch to IgG-based tests (DGP-IgG or tTG-IgG).
-
Always include total IgA
Any coeliac serology worth its salt includes a total IgA measurement in the same request. Without it, a negative IgA-based test can’t be trusted.
-
A gluten-free negative doesn’t rule out coeliac
If you stopped eating gluten before testing, a negative result means very little. You’d need a gluten challenge or HLA genetics to move forward.
-
Biopsy is still the gold standard
In adults, upper endoscopy with duodenal biopsy remains the definitive confirmation, even with strongly positive serology.
-
HLA genetics is rule-out only
About 30–40% of the population carry DQ2 or DQ8. A positive result doesn’t mean coeliac — but a negative result makes it very unlikely.
-
Pregnancy testing is fine
Coeliac serology is safe in pregnancy. Undiagnosed coeliac is associated with pregnancy complications, so testing is worthwhile if symptomatic.
-
Children need a paediatric pathway
Paediatric coeliac diagnosis follows different criteria (ESPGHAN) and should be led by a paediatric gastroenterologist.
-
Always share prior results
Previous negative serology, endoscopy reports and current diet all matter. Bring them so we don’t repeat work or misinterpret a new result.
Reading your report
A coeliac panel can look confusing. It isn’t.
However many antibodies are run, the report follows the same four parts.
A quiet reminder
A negative antibody test whilst you’re gluten-free doesn’t rule coeliac out.
If you’d like us to talk you through it before deciding next steps, just ask.
- 01 Header
Symptoms and gluten status
Your presenting symptoms, family history, and — critically — whether you’ve been eating gluten in the six weeks before the test.
- 02 Technique
Which markers were measured
Which antibodies were run (tTG, EMA, DGP), whether total IgA was included, and the laboratory’s reference ranges.
- 03 Findings

Every marker listed against its reference range, with anything raised or low flagged, plus a comment on total IgA adequacy.
- 04 Impression
The conclusion: read this first
Negative, positive and needing biopsy, or IgA deficient and needing IgG-based follow-up — plus the exact next step to take.

Frequently asked
Everything we get asked about coeliac testing.
Quick answers on what the test measures, gluten prep, IgA deficiency, genetics, biopsy and cost.
-
What does a coeliac blood panel actually measure?
The core test is anti-tissue transglutaminase IgA (anti-tTG-IgA), the antibody your immune system produces in response to gluten when you have coeliac disease. A good panel also includes total IgA (to rule out IgA deficiency), and often endomysial antibodies (EMA) and deamidated gliadin peptide (DGP) for extra sensitivity.
-
Do I need to be eating gluten before the test?
Yes — this is the most common mistake. You must be eating gluten daily (roughly two slices of wheat bread a day, or equivalent) for at least six weeks before testing. Coeliac serology relies on an active immune response, so a gluten-free diet will normalise the antibodies and give a false negative.
-
What if I’m IgA deficient?
About 1 in 40 people with coeliac disease have selective IgA deficiency, which makes standard IgA-based tests unreliable. That’s why we always check total IgA at the same time. If it’s low, we switch to IgG-based tests such as DGP-IgG or tTG-IgG.
-
What about HLA-DQ2/DQ8 genetic testing?
HLA typing is mainly useful to rule coeliac out. Around 30–40% of the general population carry DQ2 or DQ8, so a positive result doesn’t confirm coeliac — but a negative result makes it very unlikely and can be useful for people already on a gluten-free diet.
-
When is an endoscopic biopsy needed?
If your antibodies are positive — or negative but clinical suspicion is high — an upper endoscopy with duodenal biopsy is the gold-standard confirmation in adults. Paediatric diagnosis sometimes avoids biopsy under ESPGHAN criteria, but that’s a paediatric-gastroenterology call.
-
How much does a private coeliac blood panel cost in London?
Anti-tTG with total IgA is typically £75–£150. A full panel with EMA and DGP is £150–£300. Adding a consultant gastroenterology review is £350–£700, and the full pathway with endoscopy and biopsy is £2,000–£4,000.
-
Do I need a referral?
No. Private coeliac serology accepts self-referral. That said, if the test is positive you’ll want a gastroenterologist involved for the biopsy and follow-up, and we can arrange that seamlessly.
-
How quickly do I get results?
Anti-tTG and total IgA are usually back within 24–48 hours. A full panel with EMA and DGP typically takes 3–5 days. HLA-DQ2/DQ8 genotyping takes 5–7 days.
-
Can children be tested?
Yes, but paediatric coeliac testing follows a slightly different pathway (ESPGHAN criteria) and should be led by a paediatric gastroenterologist. We arrange the paediatric-experienced phlebotomist and clinician.
-
When should I see a GP urgently instead?
If you have unintentional weight loss, ongoing malabsorption, iron deficiency with signs of GI bleeding, or a family history of GI cancer, don’t rely on private serology alone — see your GP or a gastroenterologist urgently for a full assessment.
