A single stool marker for gut inflammation, commonly used to help distinguish between irritable bowel syndrome and inflammatory bowel disease when investigating ongoing gut symptoms.
1 biomarker as listed by Selph.
The Calprotectin Test measures faecal calprotectin, a protein released by white blood cells that rises with gut inflammation. It is commonly used to help distinguish between irritable bowel syndrome, which does not raise calprotectin, and inflammatory bowel disease and other causes of gut inflammation, which do.
Against the two calprotectin tests we track, its £83 price is close to the £85 median, and it is considerably cheaper than Blue Horizon Medicals' Faecal Calprotectin test at £146.25. Its 1 to 2 day turnaround is also notably faster than most of Selph's other stool-based tests, several of which take 5 to 8 days.
It scores well on clarity and documentation and Trust Signals, and its Clinical Depth score reflects that it is a single-marker test doing exactly what it sets out to do rather than being penalised for narrow coverage. Results and Follow-up benefits from doctor review of every result.
This suits you if you have ongoing gut symptoms such as bloating, diarrhoea or stomach pain and want a marker that can help distinguish inflammatory causes from non-inflammatory ones such as IBS, ideally alongside advice from your GP. If you want the same marker for similar outlay, Bluecrest Wellness' Inflammatory Bowel Disease test is priced closely at £85.
You collect a stool sample at home and post it to the lab; there is no blood-based alternative for this test. A Selph doctor reviews your calprotectin level and provides a written report with an explanation, typically within 1 to 2 days.
The Calprotectin Test measures faecal calprotectin, a marker of gut inflammation, for £83, close to the £85 median for the two calprotectin tests we track and markedly cheaper than Blue Horizon Medicals' £146.25 equivalent. Results are returned within 1 to 2 days, faster than most of Selph's other stool-based tests. The main caveat is that it is a single-marker test, so it cannot on its own identify the cause of any inflammation it detects.
The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.
