  • Descripción del producto
    Nanosphere Verigene || Each CDF test consists of a Verigene CDF Nucleic Acid Test Kit and a Verigene CDF Amplification Reagent Kit. || The Verigene Clostridium difficile Nucleic Acid Test (CDF) is a qualitative multiplexed in vitro diagnostic test for the rapid detection of toxin A (tcdA), toxin B (tcdB), and tcdC gene sequences of toxigenic Clostridium difficile and for presumptive identification of PCR ribotype 027 strains from unformed (liquid or soft) stool specimens collected from patients suspected of having C. difficile infection (CDI). Presumptive identification of the PCR ribotype 027 strain of C. difficile is by detection of the binary toxin (cdt) gene sequence and the single base pair deletion at nucleotide 117 in the tcdC gene. The tcdC gene encodes for a negative regulator in C. difficile toxin production. The test is performed on the Verigene System and utilizes automated specimen preparation and polymerase chain reaction (PCR) amplification, combined with a nanoparticle-based array hybridization assay to detect the toxin gene sequences associated with toxin-producing C. difficile. The CDF test is indicated for use as an aid in the diagnosis of CDI. Detection of PCR ribotype 027 strains of C. difficile by the CDF test is solely for epidemiological purposes and is not intended to guide or monitor treatment for C. difficile infections. Concomitant culture is necessary only if further typing or organism recovery is required.
