Coeliac
Blood Test

If you’re dealing with ongoing bloating, stomach pain, fatigue, or unexplained weight loss, this test can help uncover whether gluten might be the culprit.

End the Gut Mystery: Screen for Coeliac Disease and Gluten Sensitivity – Get Answers at Home

Persistent bloating, fatigue, or unexplained weight loss turning meals into misery? Coeliac disease, an autoimmune reaction to gluten, could be damaging your gut silently – our blood test detects key antibodies (tTG-IgA) to confirm and guide relief.

A professional nurse handles your home venous draw, with results in 7 days – the essential step to reclaim digestive ease and vitality without NHS delays.

The Gut’s Silent Saboteur – How Coeliac Disease Steals Your Comfort and Energy

Gluten in everyday bread, pasta, or beer triggers coeliac in 1% of the UK population – an immune attack on your small intestine that blocks nutrient absorption. Symptoms masquerade as IBS: chronic bloating and pain after eating, diarrhoea or constipation disrupting life, fatigue sapping drive, or rashes itching relentlessly. Iron deficiency leads to anaemia dizziness, fertility woes, or mood lows, while family history or autoimmune links (like type 1 diabetes) heighten risk.

It’s frustratingly overlooked – years of discomfort blamed on stress or diet, until malabsorption causes weight loss or bone thinning. Without diagnosis, damage accumulates; but early detection via antibodies allows a gluten-free shift, often resolving issues swiftly.

“Bloating ruled my life – the test confirmed coeliac, and going gluten-free transformed me.” – Sophie L., Cardiff.

Break free from uncertainty – testing empowers healing before it worsens.

Who Should Take the Coeliac Blood Test? If Symptoms Persist, This Could Be Key

This screen is vital for digestive or systemic clues.
Test if you’re:

  • Facing ongoing gut issues like bloating, stomach pain, diarrhoea, or constipation that diet tweaks ignore?
  • Battling unexplained fatigue, weight loss, or low mood from nutrient gaps like iron deficiency?
  • Noticing skin rashes (dermatitis herpetiformis) or anaemia signs such as pale skin or dizziness?
  • Experiencing fertility problems, irregular periods, or autoimmune overlaps (thyroid, diabetes)?
  • With family history of coeliac or restrictive eating habits that might mask symptoms?

Important: Eat gluten daily (e.g., 2-3 slices bread) for 4-6 weeks pre-test for accuracy – if gluten-free already, consult GP first. Annual screening recommended, or as symptoms flare.

What Your Coeliac Blood Test Reveals – Antibody Screening for Gluten Reaction

Our accredited UK lab tests your venous sample for immune markers, delivering a PDF report with positivity flags, explanations, and GP referral advice. Core biomarkers:

  • IgA, Tissue Transglutaminase (tTG-IgA): Detects IgA antibodies targeting gut enzyme tTG, triggered by gluten in coeliac. Elevated levels (>20 U/mL) strongly suggest the condition, prompting biopsy confirmation for diagnosis.
  • IgA (Immunoglobulin A): Measures total IgA levels to ensure test validity – low IgA (deficiency in 2-3%) might need alternative screens (e.g., IgG-based) for accurate coeliac detection.

Report notes false negatives (if gluten-avoided) and positives (rare cross-reactions), correlating with symptoms for reliable insights.

If Positive: Managing Coeliac Disease – Steps to Thrive Gluten-Free

Diagnosis opens doors to relief – coeliac is manageable lifelong with strict avoidance, restoring gut health in months for 70-80% symptom-free living. Partner with your GP or dietitian for:

  • Strict Gluten-Free Diet: Eliminate wheat, barley, rye (check labels for hidden sources like sauces); embrace oats (certified GF), rice, quinoa, fruits/veggies. Apps like “Find Me Gluten Free” help UK dining.
  • Nutrient Replenishment: Supplements for iron, B12, calcium if deficient; monitor via follow-up tests to heal absorption.
  • Symptom Relief: Probiotics for gut balance, anti-inflammatories short-term; join support like Coeliac UK for recipes and community.
  • Follow-Up: Retest antibodies annually or post-diet change; biopsy if needed for official diagnosis and benefits access.

Negative? Reassuring – explore other causes like IBS; retest if symptoms evolve. Always seek medical confirmation.

Addressing Your Doubts – Accurate, Gentle, and Empowering

  • Gluten-free already? Results may false-negative – resume gluten briefly or discuss IgG alternatives with us/GP.
  • Is it reliable? tTG-IgA is 90-95% sensitive/specific per NICE guidelines; we flag limitations.
  • Draw discomfort? Home venous by experts – quick, confidential, no clinics.
  • What next? Report guides GP referral for biopsy/treatment; early action prevents complications.
Unmask the cause – feel whole again starting now.

Other Questions

  • Ongoing digestive issues like bloating, diarrhoea, or constipation
  • Unexplained fatigue, weight loss, or low mood
  • Iron deficiency anaemia or other nutrient deficiencies
  • A family history of coeliac disease
  • An autoimmune condition like type 1 diabetes or thyroid disease
  • A skin condition like dermatitis herpetiformis
  • Gluten antibodies

Take the blood test as early as possible. Ensure you have been eating gluten weeks leading up to the test.

Collection method: Venous blood
Results available: 1-2 days after the sample has reached the laboratory.

IgA,Tissue Transglutaminase

The tTG-IgA test is one of the most commonly used blood tests to screen for coeliac disease — an autoimmune condition triggered by eating gluten, It detects IgA antibodies against tissue transglutaminase (tTG), an enzyme found in the intestine. In people with coeliac disease, eating gluten causes the immune system to produce these antibodies, which then attack the gut lining.

IgA

IgA (Immunoglobulin A) is an antibody — a type of protein produced by your immune system to help fight infections. It’s one of the five main types of immunoglobulins (IgG, IgM, IgA, IgE, and IgD), and it plays a key role in immune function, especially in mucosal areas like the respiratory and gastrointestinal tracts.
