Wimpole Street, Marylebone
People looking into inflammatory marker and bowel inflammation in Marylebone are usually looking for the Calprotectin. It belongs to our stool tests group and needs a stool sample (QFIT collection kit), which a nurse or phlebotomist collects at 22 Wimpole Street, Marylebone once the clinic opens on 1 October 2026. The laboratory typically returns a result in 5 days, and the standard price is £111 with no members’ tier.

What Calprotectin measures
Laboratories file the Calprotectin under inflammatory marker, bowel inflammation and stool test. The following sections set out how a stool tests test of this kind is measured and read.
Stool tests look at the gut from the inside: faecal calprotectin measures white cell protein released when the bowel lining is inflamed, quantitative FIT (QFIT) detects tiny amounts of blood, and faecal elastase indicates how well the pancreas is producing digestive enzymes. Microbiology tests identify the cause of infectious diarrhoea by culture, microscopy for ova, cysts and parasites, or multiplex PCR panels that detect many bacteria, viruses and parasites in one go, and stool antigen tests detect Helicobacter pylori. Faecal fat and reducing substances address malabsorption.
Preparing for your Calprotectin
- 1Collect the sample into the kit provided using the scoop or collection paper, avoiding contamination with urine or water from the toilet.
- 2For Helicobacter pylori antigen, stop proton pump inhibitors two weeks and antibiotics four weeks before the sample.
- 3Calprotectin can be raised by NSAIDs such as ibuprofen; avoid them for a week beforehand if possible.
- 4Return the sample promptly — most stool tests should reach the laboratory within 24 to 48 hours of collection, kept in the fridge if there is a delay.
Sample for this test: stool sample (QFIT collection kit).
Who considers Calprotectin
- People often consider stool testing if they have had a change in bowel habit lasting more than a few weeks.
- Diarrhoea after travel, or that has persisted beyond a week, is a common reason to look for infection.
- Those wondering whether symptoms are irritable bowel syndrome or inflammatory bowel disease frequently have calprotectin measured.
- Bloating, pale greasy stools and weight loss may prompt elastase or faecal fat testing.
- A family history of bowel cancer, or new bleeding, can lead to QFIT being requested.
Understanding your Calprotectin results
A normal calprotectin makes active inflammatory bowel disease unlikely, while a clearly raised value can indicate inflammation and usually prompts gastroenterology referral; intermediate values are frequently repeated. A positive QFIT means blood was detected and, regardless of the amount, normally leads to colonoscopy to find the source, most of which turn out to be benign. A positive pathogen result identifies a likely cause of diarrhoea and, where relevant, whether treatment is needed or the infection will settle on its own.
Stool results depend on correct collection and prompt transport, and a positive infection or blood result is a signal for further assessment rather than a final diagnosis.
