Testing for blood in your poo: the home test kit

3rd April 2024

What is a faecal-immunochemical test (FIT test)?

You may know that the NHS offers national bowel cancer screening checks, by sending you a home kit. This home kit requires you to collect a small sample of poo and send it to a lab, where they check for tiny amounts of hidden blood.

Blood can be a sign of bowel cancer, amongst other digestive conditions, so if the test finds anything unusual, you may be asked to go for further tests to rule out bowel cancer.

Screening is offered because bowel cancer is the 4th most common type of cancer. This home kit helps to find bowel cancer at an early stage when it is more treatable.

When should I expect to receive one in the post?

Unless you are over 74 years of age, you will not need to request a home test kit. The tests are sent to you in the post automatically, if you are eligible, but we have included the helplines for the bowel cancer screening programmes below in case you have any questions.

Current Research

Guts UK is the only UK charity funding research into the digestive system from top to tail. Currently, we are funding Professor Colin Rees’ COLO-COHORT Study, which aims to develop a ‘risk stratification tool’ to determine those who are at a higher risk of developing bowel cancer or polyps. This tool will be able to be used to work out which patients need to be referred to endoscopy for investigation.

Our guts have been underfunded, undervalued and undervalued for decades. We can only continue to help people with your support. Together we can do more. Please consider donating to Guts UK today.
