The Quantitative Faecal Immunochemical Test (qFIT) is used to detect occult blood in faeces. qFIT is available as part of a pilot scheme to replace the Guaiac Faecal Occult Blood test (gFOBt), which has not been available in Gloucestershire primary care for several years. The qFIT has many advantages over the gFOBt, for example, qFIT is specific to human haemoglobin so is less influenced by diet and medication than gFOBt.
