Faecal Occult Blood (FOB / QFIT) Stool Test
The Faecal Occult Blood (FOB), also known as the Quantitative Faecal Immunochemical Test (QFIT), is a stool test used to detect very small amounts of blood in the stool that are not visible to the naked eye. The presence of occult (hidden) blood can be an early sign of conditions affecting the digestive tract, including inflammation, polyps, or bowel disease.
This test is widely used as a screening and investigative tool because it is non-invasive, easy to perform, and capable of detecting early changes before symptoms become severe. Identifying hidden blood early can help guide timely further investigation when needed.

What does the FOB / QFIT test detect?
The QFIT test specifically detects human haemoglobin in the stool. Unlike older stool tests, it does not react to blood from food sources, making it more specific and reliable for detecting bleeding from the lower gastrointestinal tract.
Small amounts of bleeding can occur for a variety of reasons, including haemorrhoids, inflammation, bowel polyps, or other gastrointestinal conditions. The QFIT test helps identify whether further assessment may be needed.
Why might I need a FOB / QFIT test?
This test may be recommended if you have symptoms such as unexplained changes in bowel habits, abdominal pain, unexplained anaemia, or persistent digestive discomfort. It is also commonly used as a screening tool in people without symptoms, particularly over a certain age.
Because the test can detect very small amounts of blood, it may identify issues at an early stage, allowing further investigations to be carried out promptly if required.
What do the results mean?
A negative result suggests that no significant blood was detected in the sample. A positive result indicates the presence of blood and does not diagnose a specific condition on its own.
If blood is detected, your healthcare professional may recommend further tests such as blood tests, imaging, or referral for additional gastrointestinal assessment to determine the cause.
How is the test performed?
The test involves collecting a small stool sample at home using a provided collection device. Clear instructions are supplied to ensure accurate sampling and minimise discomfort or inconvenience.
Do I need to prepare?
No dietary changes or fasting are required for this test unless you have been advised otherwise.
