Screen for coeliac-related antibodies at home with a simple finger-prick blood test.

The Prima Coeliac Disease Screening Test checks capillary blood for anti-deamidated gliadin peptide (anti-DGP) IgG and anti-tissue transglutaminase (anti-tTG) IgA antibodies, both strongly linked to coeliac disease, an autoimmune reaction to gluten that affects the small intestine.

Who It's For

People with symptoms that may relate to coeliac disease (such as bloating, chronic diarrhoea, vomiting, constipation, weight loss, fatigue or irritability), those with a first-degree relative with coeliac disease, and people with related conditions such as Type 1 diabetes.
