Almost one in a hundred of us is coeliac. While the genes (about 20% carry them) are no more common than a generation ago, coeliac has grown 5 times more common. It is increasingly diagnosed in middle-age. The triggers are not fully known, but it’s not as simple as ‘eating too much bread’. It is more linked to overall changes to diet and lifestyle in Western countries. If you have it, you need to know - as gluten is the main driver of the symptoms and resulting health risks of coeliac disease,
Xeliac Pro is a reliable home test. It takes minutes to perform and gives a positive result if you have the typical coeliac antibodies (IgA or IgG) to Tissue Transglutaminase (tTG).
How reliable is the test?
The test has been validated against laboratory tests and shown to be very reliable (96.5% sensitivity, 97.3% specificity) when carried out in accordance with the instructions. If the test is negative and neither type of antibody has been detected, coeliac disease can be virtually ruled out.
Is it easy to carry out?
It takes under 10 minutes to get your results. The starting point is taking a fingerprick blood sample. The following video shows how the sample is taken.

Does the test still work in the 2% of coeliacs with low IgA antibody levels?
Yes - the test will give a positive result once there are IgG antibodies to tTG. The presence of at least one type of these antibodies indicates a high probability that you have coeliac disease.
The test would only give a false negative result in rare situations, such as when the levels of tTG antibodies are very low. This can happen, for example, if you’ve already eliminated gluten from your diet months before taking the test. The test would also be adversely affected if the blood sample is too small or wasn’t properly inserted into the test unit.
· Costs €28.99 plus €1 for P&P
· Uses a fingerprick blood sample
· Takes 5 minutes
· Simple yes/no answer
· You should have recent gluten exposure to do the test
· If the result is positive, you are advised to see your GP to arrange confirmation of the diagnosis by biopsy. This can confer a tax benefit (Republic of Ireland) or permit you to receive gluten-free foods on prescription (Northern Ireland).

Note: Being coeliac is not the same as being gluten- or wheat intolerant. US estimates suggest that for every coeliac, there are 10 people with gluten- or wheat-intolerance. Many of these cases would show up in the Food Detective test which detects anti-gliadin IgG and anti-wheat IgG (If you have purchased a Coeliac test from us, you are entitled to a €5 discount on a Food Detective test kit purchased within the following 12 weeks (please remind us when paying). The consequences of coeliac disease tend to be more severe than for wheat or gluten intolerance.
