[Technical detection of Helicobacter pylori: place of the antigen research in the stools]

ABSTRACT

Infection with Heliobacter pylori is the origin of different severe gastroduodenal affections, including ulcerative diseases. A large number of technical methods are available for the detection of this disease. Some are called [invasive] which require the use of endoscopy and gastric biopsy in order to obtain a sample to be analyzed. Others are [non invasive], which do not need a gastric access. The basic principles of these different techniques are reviewed. We precisely explored here the specificity, sensibility also weak and strong points of each technique. A special attention have been given to the technique based on the stool antigen research, as it is a non invasive, simple to be used, cheap, with a good sensibility and specificity results:
