Fecal Immunochemical Test (FIT) is a diagnostic technique that examines stool samples for traces of non-visible blood, which could potentially indicate conditions including bowel cancer.[1] Symptoms which could be caused by bowel cancer and suggest a FIT include a change in bowel habit, anaemia, unexplained weight loss, and abdominal pain.[2][3]

A 2022 UK guideline recommends the use of a FIT threshold of fHb ≥10 µg Hb/g to select patients with symptoms for an urgent referral for colorectal cancer investigation.[4]
