Performance analysis of two immunochromatographic assays for the diagnosis of rotavirus infection
2017
Group A rotaviruses (RVAs) are the primary cause of acute gastroenteritis (AGE) in young children worldwide. Several commercial tests including latex agglutination, enzyme-linked assays (ELISA) and immunochromatographic tests (ICT) have been developed for the diagnosis of RVA infection. In the present study, the performance of two commercially available one-step chromatographic immunoassays, CerTest Rotavirus + Adenovirus (Biotec S.L, Zaragoza, Spain) and Vikia Rota-Adeno (bioMerieux SA, Lyon, France) were retrospectively evaluated using Real-time PCR as reference test. Re-testing by Real-time PCR of 2096 stool samples of children hospitalized with AGE previously screened by ICTs (1467 by C…
Comparison of a rapid immunochromatographic test with a chemiluminescence immunoassay for detection of anti-SARS-CoV-2 IgM and IgG
2020
Introduction: The 2019 Coronavirus disease (COVID-19) has been characterized as a pandemic, representing a serious global public health emergency. Serological tests have been proposed as reliable tools for detecting Coronavirus SARS-CoV-2 antibodies in infected patients, especially for surveillance or epidemiological purposes. The aim of this study is to evaluate the agreement between the IgM/IgG rapid assays, based on lateral flow immunochromatographic assay, and the fully automated 2019-nCoV IgM and IgG, based on chemiluminescence immunoassay. Materials and methods: SARS-CoV-2 antibodies were measured with the BIOSYNEX COVID-19 BSS IgM/IgG test (BIOSYNEX, Illkirch-Graffenstaden, France) a…
Evaluación de dos equipos inmunocromatográficos comerciales para el diagnóstico rápido de la infección por rotavirus Evaluation of two immunochromato…
2008
Se realizó un estudio prospectivo para evaluar dos equipos comerciales inmunocromatográficos para el diagnóstico rápido de infección por rotavirus a partir de muestras fecales: VIKIA® Rota-Adeno, de bioMérieux, y Simple Rota- Adeno, de Operon. Como método de referencia se utilizó la transcripción reversa y reacción en cadena de la polimerasa (RT-PCR) con cebadores específicos del gen de la proteína VP7 de rotavirus del grupo A. La sensibilidad y la especificidad respecto de la RT-PCR fueron del 98,4% y 84,8% para el Simple Rota-Adeno, y del 100% y 24,2% para el VIKIA® Rota-Adeno. Es de destacar la baja especificidad de este último equipo diagnóstico, que presentó un elevado número de falsos…
