چکیده
We performed a retrospective (n = 121) and prospective (n = 305) verification of the Cepheid Xpert Flu assay to determine its performance characteristics. The overall sensitivity and specificity were 93% and 100%, respectively. Nasopharyngeal specimen sensitivities were 100% for seasonal influenza A/H1 virus and influenza A/H3 virus, 90% for influenza A/2009/H1N1 virus, and 95% for influenza B virus.

Evaluation of the Cepheid Xpert Flu Assay for rapid identification and differentiation of influenza A, influenza A 2009 H1N1, and influenza B viruses.
The Xpert Flu Assay cartridge is a next-generation nucleic acid amplification system that provides multiplexed PCR detection of the influenza A, influenza A 2009 H1N1, and influenza B viruses in approximately 70 min with minimal hands-on time. Six laboratories participated in a clinical trial comparing the results of the new Cepheid Xpert Flu Assay to those of culture or real-time PCR with arch...

Given the new diagnostic need following the pandemic caused by the A(H1N1)v virus, we evaluated the performance characteristics of Xpert® Flu assay (Cepheid). The overall sensitivity and specificity were 65.6% and 92.8%, respectively. Sensitivity and specificity for A(H1N1)v virus were 85.7% and 94.9%, respectively, and therefore the Xpert® Flu assay is suitable for a rapid diagnosis in critica...

Clostridium difficile is the most important cause of nosocomial diarrhea. Several laboratory techniques are available to detect C. difficile toxins or the genes that encode them in fecal samples. We evaluated the Xpert C. difficile and Xpert C. difficile/Epi (Cepheid, CA) that detect the toxin B gene (tcdB) and tcdB, cdt, and a deletion in tcdC associated with the 027/NAP1/BI strain, respective...
متن کاملA Reverse transcription-PCR assay for detection of type A influenza virus and differentiation of avian H7 subtype
Abstract : Avian influenza virus (AIV) infection is a major cause of influenza mortality in birds and can cause human mortality and morbidity. Although the risk of infection with avian influenza virus (AIV) is generally low for most people, the pathogenic virus can cross the species barrier and acquires the ability to infect and be transmitted among the human population; therefore the ra...
متن کاملA Sensitive Neutralization Assay for Influenza C Viruses Based on the Acetylesterase Activity HEF Glycoprotein
Influenza C virus possesses specific neuraminate-O-acetylesterase as a receptor-destroying function. This enzymatic activity of the viral glycoprotein HEF (Hemagglutinin, esterase activity and fusion factor) can be visualized in situ by the use of distinct color substrates. Hereby the localization, as well as the quantity of synthesized HEF protein is detectable. We further developed the estera...
