San Diego, CA, May 10, 2015 --(PR.com
)-- Clostridium difficile colitis is one of the most common diseases related to healthcare-associated infections (HAIs). The opportunistic bacteria C. difficile infects the human gut and releases enterotoxins and cytotoxins, causing severe diarrhea and inflammation. According to the CDC, C. difficile caused almost half a million infections in the U.S. in 2011; 29,000 deaths occurred within a month of diagnosis.
Modern diagnosis of infection involve immunoassay to detect specific C. difficile antigens, such as glutamate dehydrogenase (GDH). According to peer reviewed literature, measurement of C. difficile GDH gives satisfactory clinical diagnostic sensitivity and specificity, 100% and 99.6% respectively.
Epitope Diagnostics, Inc. has launched the EDI™ Fecal C. difficile GDH ELISA (Cat. no. KT-828), which is CE marked for in vitro diagnostic use.
This monoclonal antibody-based sandwich ELISA uniquely allows for both quantitative and qualitative detection of C. difficile GDH. Therefore, the clinical laboratory has the flexibility to perform either of these to suit patient needs. The assay has 2 hour incubation period. In-house validation study showed a 100% clinical sensitivity and specificity, with an LLOD of approximate 0.5 ng/ml.
To supplement ease of use, Epitope Diagnostics has a simple and cost effective collection tube (Cat. no. KT-889) available to handle stool samples, which can be used in conjunction with the ELISA kit.
