About this test

The Essential IBS Test measures tissue transglutaminase IgA (a coeliac antibody), C-reactive protein and faecal calprotectin (both markers of gut inflammation), and Helicobacter pylori stool antigen. Selph's own description notes that IBS itself has no blood or stool marker; the panel is instead designed to check for other conditions with overlapping symptoms, such as coeliac disease, gut inflammation and H. pylori infection, alongside a GP's clinical assessment.

It is compared here against coeliac tests, where its £199 price sits about 18% above the £169 median, but its 4 markers are well above the median of 1, since most coeliac-only tests measure just one antibody. Selph's own Coeliac Disease Blood Test tests coeliac antibodies more thoroughly (4 dedicated antibody markers) for £63, so if coeliac disease is your main concern, that panel goes deeper for less.

Clinical Depth scores highly given the marker count for its group, while value for money is more modest given the price relative to the coeliac comparison group. Collection Convenience and Results and Follow-up reflect the combined blood-and-stool format and doctor review of results.

Who is it for?

This suits you if you have ongoing gut symptoms and want several possible causes, including coeliac disease, inflammation and H. pylori, checked in one order before or alongside a GP assessment for IBS. If coeliac antibodies specifically are your main concern, Selph's own Coeliac Disease Blood Test tests four dedicated antibody markers for £63, considerably less than this broader panel.

How it works

You collect a stool sample and a finger-prick or venous blood sample at home and post them to the lab, or arrange a clinic or nurse visit for the blood component. A Selph doctor reviews the combined results and provides a written report, typically within 3 to 4 days.

Pros & cons

Pros

  • Checks four different possible causes of gut symptoms (coeliac antibodies, inflammation and H. pylori) in one order.
  • 4 markers is well above the 1-marker median for the coeliac tests we compare it against.
  • Results reviewed by a doctor within 3 to 4 days.

Cons

  • £199 is about 18% above the £169 median price in its comparison group.
  • Selph's own Coeliac Disease Blood Test tests coeliac antibodies more thoroughly for £63.
  • Does not test for IBS itself, since there is no blood or stool marker for it.
