I think there are two things. One is the CDC programme; the 160 centres and 7 million tests that we have rolled out are now very much helping in that space. However, it is also about making sure that the right people get the tests. On the question of awareness as well, we now have these faecal tests—a bit like bowel cancer screening—which can tell with 90% sensitivity whether you have inflammatory bowel disease or irritable bowel syndrome. With one, you absolutely need to see a specialist for endoscopy, while with the other, you do not. Telling the difference is key.
