Diagnostic composition containing urea for detecting the presence of Helicobacter pylori through the presence of ammonia in the exhaled breath

摘要

A medical preparation for demonstrating the presence of urease activity in the stomach in conjunction with Helicobacter pylori infection by demonstrating the presence of formed ammonia in exhalation air is claimed. The preparation comprises a solid substantially water free composition that contains non-isotopically labeled urea, which is influenced by the activity of Helicobacter pylori to form ammonia.
