METHODS. In October 2022, our system began reflex testing all PCR-positive stool samples with the C. DIFF QUIK CHEK COMPLETE (Techlab), an enzyme immunoassay–based test with results for the glutamate dehydrogenase antigen (GDH) and C difficile toxin A/B. Hospital-onset (HO) CDI and CDI ...
June 1-5.C. DIFF QUIK CHEK COMPLETE®is the only test that simultaneously detects and differentiates both glutamate dehydrogenase (GDH) antigen and toxins A&B ofClostridium difficile(C. diff)in one single device. TECHLAB®will have its team on hand to discuss their full ...
DIFF QUIK CHEK COMPLETE® test (Alere North America, Inc.). Samples were considered positive if both GDH and toxin antigens were detected. Those that were inconclusive by this method (GDH antigen positive, toxin negative) were reflexed to a molecular detection method which evaluated the ...
The C.DIFF CHEKTM is an enzyme immunoassay for use as a screening test to detect C. difficile antigen, glutamate dehydogenase,in fecal samples. The goals of this evaluation were to determine the sensitivity, specificity, positive predictivevalue, negative predictive value and correlation of the ...
diff Quik Chek Complete (Techlab Inc.) and Immunocard (Meridian Bioscience) using remnant stool samples from 262 patients with suspected CDI. RESULTS. Sofia 2 demonstrated high agreement with the EIA methods for GDH (positive percentage agreement (PPA): 100%, negative percentage agreement (NPA):...
Results Nineteen (4.6%) of 409 samples were positive for glutamate dehydrogenase (GDH) in stool and CMB by the QCC assay; seven (1.7%) were positive for both GDH and toxins A/B. The sensitivities of QCC to detect C. difficile toxin directly in stool specimens and CMB were 68.4% and ...
A total of 54 patients (3.21%; 95% CI: 2.42鈥 4.17) tested positive for both the GDH antigen and free toxin. The risk factors for CDI included the presence of co-morbidities, antibiotic usage, and immunosuppression. The detected PCR ribotypes included 053-16, 017, ...

difficile toxin and glutamate dehydrogenase antigen screen (GDH). If testing is negative for either, then nucleic acid amplification testing (NAAT) is done to confirm the diagnosis. Endoscopic evaluation may be required in rare instances when there is a high clinical suspicion of disease with ...
difficile common antigen by the C. DIFF CHEKTM test and/ or by PCR were positive for toxin B by the TC assay. Although a GDH-positive/TC-negative result may indicate growth of nontoxigenic isolates of C. difficile in the patient, we cannot rule out the possibility that some of these ...
