Differences between FIT in screening and symptomatic use

The Faecal Immunochemical Test (FIT) is used in two different pathways to assess the risk of colorectal cancer.

• When people present with colorectal symptoms, FIT can detect trace amounts of blood with a low threshold for a positive result.

• FIT is also used for asymptomatic screening with a higher positive test threshold.

Healthcare professions should ensure:

• People with symptoms are tested in line with guidance, regardless of their bowel cancer screening results.

• Eligible patients are encouraged to participate in bowel screening when they’re invited, even where they’ve had a negative symptomatic FIT.
