qFIT and calprotectin test in Chiswick

What the test measures

This test combines two stool measurements. The quantitative faecal immunochemical test, or qFIT, detects tiny amounts of human haemoglobin in your stool that cannot be seen with the naked eye. Hidden blood can come from piles, inflammation, polyps and other conditions that need investigation.

Calprotectin is a protein released by white blood cells when the lining of the bowel is inflamed. A raised level suggests inflammation, as seen in inflammatory bowel disease such as Crohn's disease and ulcerative colitis, or in infection. A normal level is reassuring that symptoms are less likely to be inflammatory, which helps clinicians decide on next steps.

The price includes a stool collection kit from our Chiswick clinic, analysis at the Randox accredited laboratory, a review of your result with an Omnia practitioner, and a GP feedback report on request.

Who it is for

• You have had a change in bowel habit, such as looser stools or more frequent visits, for several weeks.
• You have abdominal pain or bloating and want to know whether inflammation is involved.
• You have a diagnosis of inflammatory bowel disease and want to keep track of inflammation.
• Your GP has asked for a stool test to help decide on next steps.
• You have a family history of bowel conditions and want to discuss your symptoms with data.

Understanding your result

Each measurement has its own threshold, shown on your report with the laboratory reference range. A raised qFIT means blood was found and further assessment is needed to find the source, which may include referral for a camera test. A raised calprotectin points to inflammation, and mildly raised levels are often repeated before any decision is made.

An unusual value is a starting point for a conversation with your practitioner rather than a diagnosis. A normal result does not replace NHS bowel screening, and symptoms such as visible blood, unexplained weight loss or anaemia should always be reported to your GP promptly.

Preparing for your test

You collect a small stool sample at home using the pots and instructions we provide, then return it to the clinic. Avoid collecting during a menstrual period or a flare of bleeding piles, and keep the sample free of urine and toilet water. Anti-inflammatory painkillers such as ibuprofen and some stomach acid medicines can raise calprotectin, so tell us what you take when you book. No fasting is needed.

If you only need the inflammation marker, see our calprotectin test, while the H. pylori tests and coeliac blood test look at other common gut causes. For other options, you can look through every blood test and price in Chiswick.

Questions

How much is a qFIT and calprotectin test in Chiswick?

The qFIT and Calprotectin test costs £139 at our Chiswick clinic. This includes the collection kit, analysis of both markers at the Randox accredited laboratory, a practitioner review and a GP feedback report on request.

What is the difference between qFIT and calprotectin?

qFIT looks for hidden blood, while calprotectin looks for inflammation. Together they give a fuller picture of what may be causing bowel symptoms.

Is this the same as NHS bowel screening?

The NHS screening programme also uses a FIT test, but this private test is not a replacement for it. Please continue to complete your NHS screening kit when it is sent to you.

What happens if a result is raised?

Your practitioner will talk you through the result and, where needed, recommend that you see your GP for further investigation. The GP feedback report can help with that conversation.
