Diagnostic Methods


The present invention relates to novel methods for the diagnosis of Helicobacter pylori infection. Specifically, the present invention relates to novel non-invasive methods for the detection of the presence or absence of a Helicobacter pylori antigen or a metabolite produced by the bacterium in a biological sample with a biosensor-based measurement. The present invention also related to the use of a biosensor containing specific antibodies against H. pylori or antigen-binding fragments thereof immobilized thereto together with biomolecule-repellent polymers preventing the non-specific binding. The invention also relates to test kits useful in the methods.
