The BioNexia® FOBplus is a visual immunochromatographic quick test for the qualitative detection of human hemoglobin in stool samples. The test is only intended for professional in vitro diagnostic use.
The immunological Bionexia® FOB quick test is based on a immunochromatographic method, in which only human hemoglobin is recognized through specifi c antibody reactions.
The hemoglobin contained in the stool sample reacts with specifi c monoclonal antibodies that are attached to gold particles. This complex is distributed on the membrane and reaches the test band (T) on which the anti-hemoglobin is present. In the case of a positive result, the molecules from the stool sample loaded with gold-marked antibodies attach to the test band (T) and are visible by means of a pink/red coloration.
In the case of a negative result, there are no hemoglobin molecules that can attach to the test band (T) as complexes and therefore, there can also be no coloration of the test band (T).
