Evaluation of two novel chemiluminescence immunoassays for the detection of Clostridium difficile glutamate dehydrogenase and toxin A&B.
A novel immunoassay for Clostridium difficile glutamate dehydrogenase (GDH) and toxin A&B (LIAISON, DiaSorin) was compared to another GDH assay (Alere), PCR and toxigenic culture. The GDH-DiaSorin is slightly more sensitive than the GDH-Alere. Sensitivity of the Toxin-Diasorin test is in accordance to the sensitivity of other immunoassays in literature.
