Objective: To assess a new immunochromatography (ICT) test that detects glutamate dehydrogenase (GDH) antigen and Clostridium difficile toxin A/B simultaneously, and to propose an algorithm for the diagnosis of C difficile infection (CDI) based on this test. Methods: We analysed 970 stool samples. Discrepant results between GDH and toxin A/B were resolved using toxigenic culture as the reference. Results: This test enabled us to obtain a conclusive result in <30 min in 93.8% of the samples. Among the discrepant results (GDH (+)/Toxin A/B (-)), 41.7% (25/60) were found to be toxigenic C dfficile by toxigenic culture. Conclusion: This test has a high sensitivity and specificity for the diagnosis of CDI. (C) 2011 Elsevier Espana, S.L. All rights reserved.
