Principle Of The Test
The functional parts of CD Helicobacter pylori IgG test are the filter and the chromatographic membrane. Both contain immunological reagents in a dehydrated state which are rehydrated by the diluted sample during the assay process. A stationary reagent line has been applied onto the membrane. The reagent line is otherwise invisible, but if the serum or whole blood sample passing through membrane contains antibodies to the specific Helicobacter pylori antigens, the line turns distinctly red under formation of a dyed antigen-antibody-anti human IgG -complex in the test line (= reagent line). The membrane contains also another stationary line in the control window invisible before use of the test. This control line turns red during the assay process, thus indicating proper performance of the test device.
