Neutralising antibody response dynamics in patients who have recovered from COVID-19 vary greatly, and prediction of immune longevity can only be accurately determined at the individual level. Our findings emphasise the importance of public health and social measures in the ongoing pandemic outbreak response, and might have implications for longevity of immunity after vaccination.
The novel coronavirus, SARS-CoV-2 that causes COVID-19 has resulted in the death of nearly 4 million people within the last 18 months. While preventive vaccination, and monoclonal antibody therapies have been rapidly developed and deployed, early in the pandemic the use of COVID-19 convalescent plas …
Background The role and performance of various serological tests for the diagnosis of COVID-19 are unclear. This study aimed to evaluate the performance of seven commercially available serological assays for SARS-CoV-2 antibodies by testing COVID-19 cases and controls. Methods Adult patients with fever for > 5 days, admitted to a tertiary-care teaching hospital in South India, were enrolled
An anti-SARS-CoV-2 S antibody concentration ≥0.8 U/mL was considered positive. The linear range was 0.4–250 U/mL, and automated dilution was performed up to a 1:50 dilution in the cobas e analyzers. For results reported as
La RT-PCR sur prélèvement rhinopharyngé est le test de référence pour diagnostiquer une infection à Sars-CoV-2 avec une sensibilité de 95 % et une spécificité de 99,9 %. . Le prélèvement salivaire pour recherche de Sars-CoV-2 par RT-PCR présente une sensibilité inférieure au prélèvement rhino-pharyngé. .

The outbreak of 2019 coronavirus disease (COVID-19) has been a challenge for hospital laboratories because of the huge number of samples that must be tested for the presence of the causative pathogen, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Simple and rapid immunodiagnostic methods are urgently needed to identify positive cases. Here we report the development of a rapid

The purpose of this study is to monitor specific anti-severe acute respiratory syndrome coronavirus 2 (anti-SARS-CoV-2) IgG and IgM antibody production in patients with severe forms of coronavirus disease 2019 (COVID-19) using various commercially available quantitative and qualitative tests. The sera of 23 confirmed COVID-19 patients were processed for anti-SARS-CoV-2 IgG and IgM detection WGrZq.
