The evaluation of the fully automated BD MAX Cdiff assay on a panel of 100 stool samples characterized by the Xpert C. difficile assay reported a high concordance between the two molecular assays (kappa coefficient of 0.96), which makes this new assay suitable for routine detection of toxigenic Clostridium difficile.

Current guidelines recommend a two-step algorithm rather than relying solely on a single test for diagnosing infection. This algorithm starts with enzyme immunoassay (EIA) for detecting glutamate dehydrogenase (GDH) and toxins A/B, followed by nucleic acid amplification test (NAAT) for GDH-positive but toxin-negative cases. This study compared the performance of three commercial NAATs: the STANDARD M10 , Xpert , and BD MAX Cdiff assays, utilized as confirmatory testing of the two-step algorithm.

We evaluated the analytical performance of three commercial molecular assays for rapid detection of Clostridioides difficile toxin B in stool samples. The results were compared with results from the BD MAX™ Cdiff assay. We analyzed forty negative and thirty-two positive stool samples with three rapid assays: Roche cobas® Liat® Cdiff, SD Biosensor STANDARD™ M10 C.

Background: is the number one cause of hospital-acquired diarrhoea. Accurate diagnosis of is of utmost importance as it guides patient management and infection control practices. Studies evaluating the performance of commercially available nucleic acid amplification tests (NAATs) versus algorithms are lacking in resource-limited settings.

Toxigenic Clostridioides difficile infection (CDI) is a high concern because of its increasing prevalence, among both nosocomial infection and community-acquired infection contexts. A total of 1320 prospective stool samples collected on FecalSwab™ (Cary-Blair medium) were screened using BD Max™ CDIFF assay (BDM). Results were compared to the routine algorithm including immunochromatographic testing for glutamate dehydrogenase (GDH) and toxin A/B (tox) using C.

Objective: Clostridioides difficile (CD) is the most common cause of nosocomial diarrhea. Detection of CD toxin in patients' faecal samples is the traditional rapid method for the diagnosis of CD infection. Various testing algorithms have been proposed: an initial screening test using a rapid test, and a confirmatory test (cytotoxicity neutralization assay, toxigenic culture, nucleic acid amplification test) for discordant results.
