Gluten intolerance is a common and treatable condition in which gluten found in wheat, barley and rye triggers an immune reaction and chronic inflammation of the small intestine. The inflammation affects the absorption of a number of essential nutrients including Calcium, Vitamins D and B12, Folate and Ferritin.
Gluten intolerance classically gives gastrointestinal symptoms including diarrhoea, indigestion, bloating, stomach pain and constipation. However, as it can present itself in more subtle ways such as fatigue or an itchy rash, it often remains undiagnosed.
Gluten intolerance and coeliac disease affect 1 in 100 people in the UK. It’s probably much more common than you may have thought. Under diagnosis is a big problem – research suggests around 500,000 people have not yet been diagnosed. If your tTG test comes back as positive, it’s important to remember you will need to undergo a biopsy using an endoscope (which your GP can arrange) in order to confirm the diagnosis. Equally, if your blood test result is negative, your GP may consider sending you for a biopsy anyway, dependent on your symptoms. It’s important to note that you must continue to eat a gluten containing diet for at least 6 weeks before the blood test to ensure accurate results.
All our tests have been specially designed to be convenient and non-invasive. Once you’ve booked your appointment, full preparation instructions will be provided in your confirmation email or letter. You can continue to eat and drink normally before your appointment, and you’ll also remain fully clothed throughout.
