BiocardTM Celiac GLUTEN Self-Test

Available in pharmacies or online :  

Abdominal pain, digestive disorders, weight loss, fatigue...

650,000 people in France are unaware that they are gluten intolerant.

Gluten intolerance is also called coeliac disease, which is an autoimmune condition.

With just one drop of blood, the Gluten Self-Test effectively tests for gluten intolerance :

  • Easy to use

  • Based on the specific detection of tissue transglutaminase IgA antibodies

  • Easy-to-read results in 5 to 10 minutes


Attention, les kits commercialisés à partir d'avril 2017 contiennent une micropipette et non un capillaire de prélèvement. Merci de se référer à la rubrique "Téléchargement des notices"

Who is it for ?

In France, coeliac disease affects 1 person out of 100 or a total of 650,000 people1.

The disease is more common in women : ratio of 2 women for 1 man2.

On average, only 1 person out of 4 is diagnosed2.

Coeliac disease affects both children and adults. There are two at-risk profiles :

  • children and siblings of coeliac patients

  • people with conditions often associated with coeliac disease : autoimmune diseases (type 1 diabetes, active chronic hepatitis), Down's syndrome, Turner syndrome, etc.

  • patients with osteoporosis at an unsual age

  • women with fertility disorders, repeated miscarriages


The  BiocardTM Celiac GLUTEN Self-Test is also intended for patients diagnosed with coeliac disease and treated for more than 6 months (who are following a gluten-free diet).

The self-test can also help these patients to make sure that the tissue transglutaminase IgA antibodies have disappeared from their body and therefore that their diet no longer contains any gluten.

Why ?

Patients with undiagnosed gluten intolerance are at risk of developing :

  • digestive disorders
  • nutrient and vitamin absoprtion disorders
  • osteoporosis
  • fertility disorders
  • cancer
  • growth retardation in children


Coeliac disease is an autoimmune disease:

  • Gluten acts as a food antigen (substance foreign to the body that is able to trigger an immune reaction by developing antibodies). These antibodies include tissue transglutaminase IgA antibodies
  •  It causes chronic inflammation of the intestines

The clinical signs that point to gluten intolerance include :

  • digestive symptoms (nausea, vomiting, intestinal disorders, etc.)
  • and/or non-digestive symptoms (mental, dermatological and/or muscular disorders, deficiencies, etc.)
  • autoantibodies detected following the intake of gluten

Clinical signs alone are not sufficient to diagnose coeliac disease. Serological diagnosis is a crucial step1,2,3,4.

The BiocardTM Celiac GLUTEN Self-Test reveals the presence of tissue transglutaminase IgA antibodies that may be associated with coeliac disease. 

The BiocardTM Celiac GLUTEN Self-Test examines the same parameter as the laboratory test.

Potential serious health consequences can be avoided by detecting gluten intolerance early.

This gluten intolerance testing can be done at home using the BiocardTM Celiac GLUTEN Self-Test in the Health self-testing line of products.
