چکیده
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 <30min in 93.8% of the samples. Among the discrepant results (GDH (+)/Toxin A/B (-)), 41.7% (25/60) were found to be toxigenic C. difficile by toxigenic culture. CONCLUSION This test has a high sensitivity and specificity for the diagnosis of CDI.

Evaluation of a new immunochromatography test for rapid and simultaneous detection of Clostridium difficile antigen and toxins.
BACKGROUND Clostridium difficile infection is considered the most common cause of nosocomial infectious diarrhea among adults in the developed world. It is responsible for virtually all cases of pseudomembranous colitis. The Tox A/B enzyme immunoassay (EIA) is the most widely used test for the detection of C. difficile toxins A and B. However, it is associated with poor sensitivity and an unacc...
متن کاملEvolution of testing algorithms at a university hospital for detection of Clostridium difficile infections.
We present the evolution of testing algorithms at our institution in which the C. Diff Quik Chek Complete immunochromatographic cartridge assay determines the presence of both glutamate dehydrogenase and Clostridium difficile toxins A and B as a primary screen for C. difficile infection and indeterminate results (glutamate dehydrogenase positive, toxin A and B negative) are confirmed by the Gen...
متن کاملComparison of five assays for detection of Clostridium difficile toxin.
Performance characteristics of five assays for detection of Clostridium difficile toxin were compared using fresh stool samples from patients with C. difficile infection (CDI). Assays were performed simultaneously and according to the manufacturers' instructions. Patients were included in the study if they exhibited clinical symptoms consistent with CDI. Nonmolecular assays included glutamate d...

We evaluated the new C. DIFF QUIK CHEK COMPLETE (CD COMPLETE; TechLab, USA), which is a rapid membrane enzyme immunoassay that uses a combination of glutamate dehydrogenase (GDH) antigen and toxin A and B detection. A total of 608 consecutive loose stool specimens collected from the patients with suspected Clostridium difficile infection (CDI) from August to December 2012 were subjected to the ...
متن کاملEvaluation of the C.Diff Quik Chek Complete Assay, a new glutamate dehydrogenase and A/B toxin combination lateral flow assay for use in rapid, simple diagnosis of clostridium difficile disease.
The diagnosis of Clostridium difficile infection continues to be a challenge for many clinical microbiology laboratories. A new lateral flow assay, the C.Diff Quik Chek Complete assay, which tests for the presence of both glutamate dehydrogenase (GDH) and C. difficile toxins A and B, was evaluated for its ability to diagnose C. difficile disease. The results of this assay were compared to those...
