A rapid urease test kit (the kind of test known as CLOtest, or CLO test) shows Helicobacter pylori urease activity in a gastric biopsy specimen taken at gastroscopy. It is an in-vitro test. The colour change is read by eye within minutes at the endoscopy table, so no analyser is needed and the specimen is not transported before the result.
This page is intended for healthcare professionals.
A rapid in-vitro diagnostic test kit that detects Helicobacter pylori urease activity in gastric biopsy specimens during endoscopy.
A rapid urease test is an in-vitro test on a gastric biopsy specimen that shows the urease activity of Helicobacter pylori. The colour change is read by eye within minutes. It uses the biopsy specimen already taken at gastroscopy, so there is no extra pass with the forceps.
The test is done on the biopsy specimen taken at gastroscopy and read at the endoscopy table, and the result is available within minutes. The colour change is read by eye, so eradication can be discussed in the same visit. This page does not give a fixed reading time or sensitivity figures.
A positive result means that urease activity was seen in the biopsy specimen, and the test shows the urease activity of Helicobacter pylori. Biopsy-based tests lose sensitivity during bleeding, and the ESGE advice on peptic ulcer bleeding on this site is to look for Helicobacter pylori in the acute phase and to repeat the test if the result is negative (Gisbert and Abraira, Am J Gastroenterol 2006;101:848-863). Reading the result and deciding on treatment belong to the physician.
CLO test is used in everyday language for the whole class of rapid urease tests, and CLOtest is one of the names under which this kind of test is known. This page describes a rapid urease test for gastric biopsy specimens taken at gastroscopy, which belongs to that class. It makes no claim that it is better than another test, and it says nothing about the availability of other products.
The rapid urease test is done on a gastric biopsy specimen, so it is used in a patient who is having a gastroscopy. Breath, stool and blood tests do not need an endoscopy. Which test to use is the physician's decision.
