I came across Test Your Intolerance on Google and ordered a test straight away. I didn’t have to wait for the post which I liked, but I don’t have a printer which they don’t warn you about! I used a friends printer and my results came through quickly. A+

Sofia McCarthy Via Google

I bought a test for my whole family and we all had issues which we’ve changed and now we feel much better. Very easy service and I’m surprised at how cheap it was!
