A positive signal in the test indicates the presence of C.difficile in the stool sample. Subsequent analysis of the sample with a test for detecting C.difficile toxins (such as our 2A-Bdiff test) confirms whether the strain is toxigenic and, therefore, pathogenic and disease-causing.
Some of the leading healthcare societies propose the use of a two-step protocol for identifying toxigenic C.difficile involving an initial screening of the sample with a GDH test and, if the result is positive, use of a second test to detect toxins from C.difficile as not all strains of this microorganism produce them.
Bio-Medical offers the possibility of following this protocol using its GDH and 2A-Bdiff tests.
