Faecal calprotectin tests are a really effective way of diagnosing irritable bowel syndrome, or the need for further examination for things such as Crohn's and colitis, which I know you've just been discussing. IBS is common, affecting up to 25 per cent of the UK population and, in general, it can be managed in primary care. However, as the symptoms can be difficult to differentiate from inflammatory bowel disease, many patients are still referred and account for 28 per cent of gastroenterology appointments—I've been practising that word all morning. These tests can help reduce these referrals by differentiating between the two conditions. Calprotectin is recommended by the National Institute for Health and Care Excellence in adults with a recent onset of lower gastrointestinal symptoms for whom a specialist assessment is being considered and when cancer is not suspected. But, in the Cwm Taf Morgannwg University Health Board, 38 per cent of those waiting for treatment on gastroenterology are waiting over 36 weeks for treatment, and 831 are waiting over a year for treatment. Therefore, what steps is the Minister taking to ensure that primary care settings are making more use of those tests where relevant, and what engagement have you had with stakeholders regarding that?
