Bowel Cancer Risk Screening Package: Non-Invasive QFiT Test
Discover how the non-invasive QFiT bowel cancer risk screening test works, who should consider it, and what your results may indicate. Available privately in London.
Bowel cancer is one of the most common cancers in the UK, yet when identified early through appropriate screening, the outcomes are often considerably more favourable. The non-invasive QFiT bowel cancer risk screening test has become a trusted first-line assessment tool — offering individuals a straightforward, private, and clinically relevant way to understand their colorectal health without the need for invasive procedures. For broader context on why early checks matter, see why preventive screening saves lives.
This article explains what the QFiT test involves, who may benefit from it, what results may indicate, and how private health screening in London supports proactive bowel health awareness.
What Is the QFiT Bowel Cancer Risk Screening Test?
The Quantitative Faecal Immunochemical Test (QFiT) is a non-invasive stool-based test that detects trace amounts of human blood in a faecal sample. Unlike older guaiac-based faecal occult blood tests, the QFiT uses antibodies specifically targeting human haemoglobin, making it more precise and reliable.
In 40–50 words: The QFiT test analyses a small stool sample to detect hidden blood that is not visible to the naked eye. It is used as a first-line, non-invasive bowel cancer risk screening tool to help identify individuals who may benefit from further clinical assessment.
This test does not diagnose bowel cancer. It may indicate whether further evaluation by an appropriate healthcare professional is warranted.
Why Bowel Cancer Screening Matters in the UK
Bowel cancer affects approximately 43,000 people in the UK each year and is the second most common cause of cancer-related death (Cancer Research UK, 2024). The majority of bowel cancers develop slowly from pre-cancerous polyps over several years — making proactive screening a meaningful step in understanding your risk profile.
Many people with early-stage bowel changes experience no obvious symptoms, which is precisely why structured, periodic screening is considered valuable by NHS England and clinical bodies including the UK National Screening Committee (UK NSC).
> Practical Insight: Early-stage bowel changes are often silent. A non-invasive QFiT test may help flag potential concerns before symptoms become apparent, allowing you to seek appropriate follow-up at the right time.
QFiT vs. Traditional Bowel Tests: A Quick Comparison
| Feature | QFiT Test | Guaiac Faecal Occult Blood Test (gFOBT) | Colonoscopy |
|---|---|---|---|
| Invasive? | No | No | Yes |
| Dietary restrictions required? | No | Yes (avoid certain foods) | Yes |
| Detects human blood specifically? | Yes | No (non-specific) | N/A |
| Quantitative result? | Yes | No | N/A |
| Suitable as first-line screen? | Yes | Older alternative | Follow-up tool |
| Available privately? | Yes | Limited | Yes |
| NHS bowel screening use? | Adopted as standard | Being phased out | Post-positive result |
The QFiT test is now the preferred method used within the NHS Bowel Cancer Screening Programme across England, Scotland, and Wales, having replaced the gFOBT due to its greater sensitivity and specificity for human haemoglobin detection (NHS England, 2019).
Who Should Consider a Bowel Cancer Risk Screening Package?
A QFiT-based bowel cancer risk screening package may be worth considering for individuals who:
- Are aged 45 or over, particularly those not yet enrolled in NHS screening
- Have a family history of bowel cancer or hereditary colorectal conditions
- Experience unexplained changes in bowel habit (seek appropriate medical advice if symptoms are present)
- Are approaching or have passed the NHS screening age threshold and want earlier reassurance
- Prefer the privacy and flexibility of a self-directed health screening approach
- Are managing conditions associated with elevated bowel cancer risk, such as inflammatory bowel disease (always discuss with your healthcare provider)
- Want to include bowel health as part of a comprehensive preventive screening package
> Practical Insight: If you are currently experiencing bowel symptoms such as rectal bleeding, persistent changes in bowel habit, or unexplained weight loss, you should seek appropriate medical care rather than relying solely on a screening test.
Private health screening in London allows individuals to access QFiT testing outside of the NHS pathway, providing timely results and supporting informed decisions about follow-up care.

How the QFiT Test Works: Step by Step
The QFiT test involves a simple process:
- Sample collection: A small stool sample is collected at home using a provided collection kit
- Sample submission: The sample is returned to the clinic or sent to an accredited laboratory
- Laboratory analysis: The sample is analysed for trace amounts of human haemoglobin using immunochemical detection
- Results reporting: A quantitative result is provided, typically expressed in micrograms of haemoglobin per gram of stool (µg Hb/g)
- Results interpretation: Results are reported with clear contextual guidance, indicating whether the level detected is within a normal range or may suggest further assessment is appropriate
No bowel preparation, dietary restrictions, or clinic procedures are required, making it an accessible option for many individuals.
Understanding Your QFiT Results: What They May Indicate
QFiT results are quantitative, meaning they provide a numerical value rather than simply a "positive" or "negative" reading.
A result below the clinical threshold may suggest that no significant hidden blood was detected in the sample provided. This can be reassuring, though it does not entirely exclude the possibility of bowel changes.
A result at or above the clinical threshold may indicate the presence of blood in the stool, which can be caused by a range of conditions — not only bowel cancer. These may include:
- Haemorrhoids (piles)
- Anal fissures
- Inflammatory bowel conditions
- Benign polyps
- Or, in some cases, more significant bowel changes
A result above the threshold does not confirm a diagnosis. It may indicate that further evaluation by an appropriate healthcare professional is recommended.
> Practical Insight: A QFiT result provides one valuable piece of information within a broader clinical picture. It is always advisable to discuss your results and personal health history with a qualified healthcare professional who can guide appropriate next steps.
When reviewing your report, it also helps to understand how reference ranges are interpreted so you can discuss results more confidently with a healthcare professional.
How Often Should You Consider QFiT Screening?
Within the NHS Bowel Cancer Screening Programme, individuals between the ages of 50 and 74 are invited for QFiT screening every two years. Private screening can complement this by:
- Offering testing to individuals below the NHS age threshold who have risk factors
- Providing more frequent testing for those with elevated personal or family risk
- Allowing testing for individuals who miss or opt out of NHS invitations
The appropriate frequency of private QFiT screening will depend on your individual circumstances, previous results, and healthcare professional guidance.

Frequently Asked Questions: QFiT Bowel Cancer Risk Screening
What is the QFiT bowel cancer risk screening test?
The QFiT (Quantitative Faecal Immunochemical Test) is a non-invasive stool test that detects hidden human blood in a faecal sample. It is used as a first-line bowel cancer risk screening tool to help identify individuals who may benefit from further clinical assessment by an appropriate healthcare professional.
Is the QFiT test painful or invasive?
No. The QFiT test requires only a small stool sample collected at home using a simple collection kit. There is no physical examination, no bowel preparation, and no dietary restrictions required prior to testing, making it a comfortable and straightforward screening option.
Can the QFiT test diagnose bowel cancer?
No. The QFiT test is a risk screening tool, not a diagnostic test. A positive result may indicate the presence of hidden blood in the stool, which can have several causes. Any result above the clinical threshold should be discussed with an appropriate healthcare professional for further evaluation.
Who should consider a QFiT bowel cancer screening package?
Individuals aged 45 and over, those with a family history of bowel cancer, and anyone seeking proactive bowel health awareness may find QFiT screening beneficial. It can also support those who have not yet received or responded to an NHS screening invitation.
How accurate is the QFiT test?
The QFiT test is a widely validated non-invasive bowel cancer screening tool, and is the method currently adopted by the NHS Bowel Cancer Screening Programme across England, Scotland, and Wales. It has a higher sensitivity and specificity for human haemoglobin detection than older guaiac-based tests. However, no single screening test is 100% accurate, and results should always be considered alongside a broader clinical assessment.
What does a positive QFiT result mean?
A result above the clinical threshold may suggest the presence of blood in the stool. This can be caused by various conditions including haemorrhoids, polyps, or inflammatory conditions — not only bowel cancer. A positive result does not confirm a diagnosis and should be reviewed by an appropriate healthcare professional.
How soon will I receive my QFiT results?
Results are typically available within a few working days of laboratory analysis. At Health Screening Clinic, results are reported clearly with contextual guidance to help you understand what your result may mean.
Is private QFiT testing available in London?
Yes. Private QFiT bowel cancer risk screening is available at nurse-led clinics in London, including Health Screening Clinic. Private testing offers flexibility, timely results, and access to screening outside of the standard NHS invitation pathway.
Does the QFiT test replace a colonoscopy?
No. The QFiT test is a non-invasive, first-line screening tool. A colonoscopy is an invasive procedure typically recommended following a positive QFiT result as part of clinical follow-up. The two serve different purposes within the screening and diagnostic pathway.
Can I combine QFiT testing with other health checks?
Yes. QFiT testing can be included as part of a broader preventive health screening package. Combining bowel cancer risk screening with other blood tests and health checks can provide a more comprehensive overview of your current health profile.
