Introduction: The SARS-CoV-2 virus is a positive-strand RNA virus. The virus can also be detected in many different specimens as throat swabs, nasal swabs, sputum, saliva, blood, etc. Objective: The aim of this paper is to compare the reliability of different types of specimen collection, saliva and s...
ABSTRACT In the pandemic, rapid and accurate detection of SARS-CoV-2 is crucial in controlling the outbreak. Recent studies have shown a high detection rate using saliva/oral fluids as specimens for laboratory detection of the virus. We intended to evaluate the test performance of the Xpert Xpress SARS-C...

BACKGROUND The high demand for adequate material for the gold standard reverse transcription real-time polymerase chain reaction (RT-qPCR)-based diagnosis imposed by the Coronavirus disease 2019 (COVID-19) pandemic, combined with the inherent contamination risks for healthcare workers during nasopharyng...
BACKGROUND Coronavirus disease 2019 (COVID-19) is highly infectious causing millions of deaths worldwide. Nasopharyngeal swabs are the primary sample of choice for the diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), thus, to decrease the exposure to potentially infected sample...
RESUMEN: El coronavirus tipo 2, SARS-CoV-2, que causa la enfermedad denominada por la OMS como COVID-19, se ha expandido provocando una pandemia desde 2019, sin cura hasta la fecha. El mecanismo de transmisión del SARS-CoV-2 entre humanos es mediante las secreciones generadas durante la respiración y e...
Resumen Introducción: El cáncer de nasofaringe es una patología poco común que tiene gran impacto en la calidad de vida de los pacientes. Con el advenimiento de nuevos esquemas de tratamiento se ha logrado mejorar el pronóstico con un menor índice de morbilidad. Esta revisión describe la perspecti...
SUMMARY BACKGROUND Healthcare personnel are at risk of becoming infected while taking upper and/or lower respiratory tract specimens. Therefore, there is a need for sampling methods that do not risk infecting them. In this study, we aimed to compare the saliva and Oro-Nasopharyngeal Swab (ONS) sampling ...
ABSTRACT The accuracy of commercially available tests for COVID-19 in Brazil remains unclear. We aimed to perform a meta-analysis to describe the accuracy of available tests to detect COVID-19 in Brazil. We searched at the Brazilian Health Regulatory Agency (ANVISA) online platform to describe the pooled...
