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 predictive value, negative predictive value and correlation of ...
DIFF QUIK CHEK COMPLETE (QCC; TechLab), which detects glutamate dehydrogenase (GDH) antigen (QCC-Ag) and toxin A/B (QCC-Tox) simultaneously, and compared it to the laboratory diagnostics for CDI currently in use in a tertiary hospital setting with a high prevalence of CDI. QCC, RIDASCREEN...
C. DIFF QUIK CHEK COMPLETE® is the only test that simultaneously detects and differentiates both glutamate dehydrogenase (GDH) antigen and toxins A&B of Clostridium difficile (C. diff) in one single device. TECHLAB® will have its team on hand to discuss their full line...
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 ...
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, ...

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 ...
A C. diff quick check complete® test (Abbott, Wavre, Belgium) for toxins and glutamate dehydrogenase antigen detection (GDH) was performed on each faeces sample (see Table 1). Confirmation with a specific qPCR test using 16S rDNA on DNA extracted from faeces was performed with the ...
In the first stage, it is recommended to complete a highly sensitive test-nucleic acid amplification test (NAAT) or enzyme immunoassay to detect glutamate dehydrogenase (EIA GDH). In the case of a positive result in the second stage, enzyme immunoassays are used to detect toxins A and B. A...
