| 摘要 |
<p>The invention relates to a diagnostic device comprising a first electrode (4) which is produced of an acid-fast noble metal, and a second electrode (5) which is produced of silver, the first electrode (4) and the second electrode (5) being at least partially immersed in a container (2) which is filled with a nutrient solution (3) and into which a tissue sample (6) can be introduced. An electrical voltage can be applied between the first electrode (4) and the second electrode (5) and a change in an electric variable can be measured between the first electrode (4) and the second electrode (5) when ammonia is present. The diagnostic device according to the invention allows the fast screening of a fresh tissue sample for Helicobacter pylori.</p> |
