Faecal Immunochemical Test (FIT)

NCL Wide
Add to CPD
Under Review — this page was due to be reviewed by Friday, 29 April 2022. The information shown here may be outdated.

Practices are reminded that Faecal Immunochemical Test (qFIT/FIT) samples for symptomatic patients should be clearly labelled and sent to local laboratories. Any symptomatic samples sent to the Bowel Screening Hub will not be processed. Please see downloads for the differences between FIT for symptomatic patients and FIT for screening.

From 1 April 2019, the FIT test for suspected colorectal cancer has been available to NCL GP Practices.

Offer a FIT test before referring to assess for colorectal cancer in adults in both low-risk (DG30) and high-risk (NG12) cases with lower GI symptoms who meet the following criteria below. Those patients who have iron deficiency anaemia, rectal or anal mass, or anal ulceration should be referred straight onto the Lower GI (LGI) 2ww for suspected colorectal cancer (CRC) pathway. 

Low risk (DG30) symptomatic

DG 30 criteria in adults without rectal bleeding:

  • ≥ 50 years with unexplained abdominal pain or weight loss
  • <60 years with changes in bowel habit
  • <60 years with iron-deficiency anaemia
  • ≥ 60 years with anaemia, but without iron deficiency

 NICE NG12 urgent referral criteria

  • ≥ 40 years with unexplained abdominal pain AND weight loss 
  • >50 with unexplained rectal bleeding 
  • > 60 with iron deficiency anaemia OR change in bowel habit 
  • < 50 with rectal bleeding AND any one of following abdominal pain, change in bowel habit, weight loss or iron deficiency anaemia 

See Downloads for the NCL LGI pathway FAQ for GPs document.

  • Ask the patient to take the sample as per the instructions on the patients leaflet (see Downloads) It is essential for the sample to be taken as soon as the faeces is produced as it deteriorates quickly. Sample must also be sent with correctly completed tQUEST / SunQuest ICE form to avoid delays in getting back results.
  • Refer to the FIT for patients presenting with bowel symptoms video (See Related Video) and  the FAQs (see Downloads) for information about the FIT test in NCL.
  • The test can be found in EMIS pathology tests under FIT (Faecal Immunochemical Test).
  • FIT for symptomatic patients is the same test as the FIT used in the National Bowel Cancer Programme. However the cut off level for positivity is much higher in the screening programme (120µg/g faeces vs. 10µg/g faeces). It is therefore important to request a FIT for a symptomatic patient even if he recently returned a bowel cancer screening FIT.

FIT <10 NG12 follow-up clinic on Lower GI pathway

From 30 April 2021 a separate, non-2WW, referral pathway to the existing LGI urgent cancer pathway was introduced as  part of a 1 year service evaluation programme. Instead of safety netting this cohort of patients in primary care, GPs should now refer patients with the following referral criteria to secondary care via ERS on the FIT <10 safety netting pathway:

  • Symptoms meeting NG12 criteria for suspected CRC
  • FIT concentration <10 µg/g
  • Absence of any of the following: iron deficiency anaemia, rectal mass, anal ulceration

The NCL protocol for this pathway is as follows: 

  • referral received via ERS on ‘FIT <10 NG12 follow-up pathway’
  • referral checked for completeness and missing information sought from GP
  • patient wil be booked by the hospital for repeat bloods (FBC), FIT and a virtual follow-up clinic in 8-10 weeks
  • consultant led virtual/ telephone clinics to determine management plan
  • options are D/C to GP, consultant upgrade onto urgent cancer pathway, further investigations on RTT pathway

This cohort of patients will be tracked based on referral source on a specific tracking list in order to differentiate them from the Two Week Wait (2WW) and referral to treatment (RTT) patient tracking list (PTL). This differentiation means that the safety netted patients will not distort 2WW performance reporting and will be easy to identify.

SMS reminders now available for GPs ordering FIT kits for patients

NHS England has implemented SMS reminders in all GP practices to remind patients to return their FIT kits to the practice for analysis. North Central London has a relatively low FIT uptake compared to the rest of the capital (only around 65% of 2ww suspected cancer referrals have an accompanying FIT result) so SMS reminders should be helpful.
FIT is an important tool in stratifying a patient’s risk of having bowel cancer but the overall usefulness of FIT relies on the test being completed and returned before the 2ww suspected cancer referral is made to secondary care.

 The SMS reminder function now sits within EMIS. Accrux, the company which manages the SMS reminder software, has prepared some helpful information on using the SMS reminders:

For most practices, there will be no additional charge associated with using the reminders, as it is likely that Accrux is already in use for SMS appointment reminders and/or video consultations.

If you would like to implement SMS FIT reminders but are not currently using Accrux please get in touch with the North Central London Cancer Alliance to explore other options for doing this. We are also investigating how we can automate these messages to be sent when a FIT kit is ordered for a patient. More information will follow on this in due course.
