Bowel cancer screening

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 be 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.
