Detection of Clostridium difficile antigen and toxin in stool specimens: Comparison of the C. difficile quik chek complete enzyme immunoassay and GeneXpert C. difficile polymerase chain reaction assay
BACKGROUND/AIMS Accurate and rapid laboratory diagnosis of Clostridium difficile infections (CDI) remains a significant challenge. A two-step algorithm for detection of toxigenic C. difficile in stool based on initial screening for glutamate dehydrogenase assay followed by confirmation by toxin A+B detection using an enzyme immunoassay (EIA) or molecular assay has been proposed. We aimed to eva...
متن کاملAlgorithm proposal based on the C. Diff Quik Chek Complete ICT device for detecting Clostridium difficile infection.
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 referen...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
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...
