tTG-IgA is the primary coeliac screen, with DGP and total IgA completing the coeliac serology picture. Faecal calprotectin adds a stool marker that distinguishes gut-wall inflammation (IBD) from the function-based symptoms of IBS. Together they address the most common gut questions before any referral.
You must be eating gluten regularly for coeliac results to be reliable; Do not start a gluten-free diet before testing; Stool sample collected at home using a kit provided at the collection centre; Avoid anti-inflammatory medicines (NSAIDs) before the stool test where possible
If you have recently reduced gluten, discuss timing with a health practitioner; Calprotectin can rise temporarily after a gut infection or NSAID use
Health practitioners use coeliac serology and calprotectin together to narrow down gut symptoms. A positive coeliac screen is confirmed before any diagnosis or dietary change. An elevated calprotectin may prompt further bowel investigation.
Pick a test or panel and check out. No GP referral, no waiting room.
