🌾 Coeliac / Gluten Sensitivity Blood Test at Prescriptions Pharmacy

Coeliac Disease Antibody Screening Blood Test in Prescot – £200

🧬 What Does This Test Check?

This test includes the key markers used in coeliac screening:

🧪 Tissue Transglutaminase Antibodies (tTG-IgA)

🧪 Deamidated Gliadin Peptide Antibodies (IgG)

🧪 Total Immunoglobulin A (Total IgA)

🔍 What Do These Markers Mean?

🧪 Tissue Transglutaminase (tTG-IgA)

This is the primary screening test for coeliac disease. It detects antibodies produced when the immune system reacts to gluten. It is considered the first-line test in most cases. :contentReference[oaicite:0]{index=0}

🧪 Deamidated Gliadin Peptide (DGP-IgG)

This test detects immune responses to gluten-related proteins and is particularly useful in patients who may have IgA deficiency or where additional confirmation is needed. :contentReference[oaicite:1]{index=1}

🧪 Total IgA

This measures overall IgA levels to ensure the accuracy of the test. Around 2–3% of people with coeliac disease have IgA deficiency, which can otherwise lead to false-negative results. :contentReference[oaicite:2]{index=2}

💡 Using these markers together improves the accuracy of coeliac disease screening and reduces the risk of false results.

⚡ What Is Coeliac Disease?

Coeliac disease is an autoimmune condition where the immune system reacts to gluten (a protein found in wheat, barley and rye), causing inflammation and damage to the lining of the small intestine.

This can lead to poor absorption of nutrients and a wide range of symptoms.

Common symptoms include:

😴 Fatigue

💨 Bloating and abdominal discomfort

🚽 Diarrhoea or digestive issues

⚖️ Unexplained weight loss

🧲 Iron deficiency

💡 Blood tests detect antibodies produced as part of this immune response to gluten. :contentReference[oaicite:3]{index=3}

👩‍⚕️ Who Is This Test Suitable For?

This test may be suitable if you:

🌾 Have symptoms linked to gluten intake

😴 Experience unexplained fatigue

💨 Have ongoing digestive symptoms

🧲 Have iron deficiency or nutritional deficiencies

👨‍👩‍👧 Have a family history of coeliac disease

📌 You should continue eating gluten before testing, as avoiding it may affect results.

⚠️ Important Information

❗ This test is a screening test and does not confirm a diagnosis on its own.

📄 If results suggest coeliac disease, you should be referred to your GP or a specialist for further assessment, which may include additional testing or biopsy.

💡 Diagnosis should always be made by an appropriate healthcare professional.

🔍 Why Is This Test Useful?

Coeliac disease can often go undiagnosed because symptoms can be mild, vague or mistaken for other conditions.

This test helps identify whether your immune system is reacting to gluten, providing a clear starting point for further investigation.

✔️ Uses recognised coeliac screening markers ✔️ Helps detect possible immune response to gluten ✔️ Supports early identification and further referral
