To quickly assess the immune response to SARS-CoV-2 of patients and entire 
communities, Sentinel Diagnostics - an Italian company focused for more than 35 
years on the development and production of In Vitro Diagnostics for the most 
advanced Clinical Chemistry, Immunochemistry and Molecular Diagnostics 
platforms - announces the launch of two new serological tests for the detection 
of total antibodies (IgA, IgG and IgM) to SARS-CoV-2 specific proteins in human 
serum: COVID-19 Anti-S1 Total Ab and COVID-19 Anti-NC Total Ab.

The application of these tests would help to identify those individuals who 
have correctly developed antibodies after infection and/or vaccination, 
supporting the understanding of the degree of diffusion of COVID-19 in the 
community and the results of the efforts made by countries for vaccination 
campaigns. "The spread of the SARS-CoV-2 pandemic and the current ongoing 
vaccination campaigns have raised the need for quick evaluation of the 
immunological status of individuals and communities to understand what measures 
to adopt in order to avoid spreading of infection, but also to monitor the 
immune response after vaccination," explains Marco Buonaguidi, Head of Sales 
and Marketing. "We have developed our new quick solution that supports the 
continuous monitoring of epidemic to ensure public health decisions delivering 
fast results."

Both COVID-19 Anti-S1 Total Ab and COVID-19 Anti-NC Total Ab assays are In 
Vitro Diagnostic tests, for quantitative and qualitative analysis with 
immunoturbimetric method, designed to process hundreds of results in 1 hour and 
thousands in a single day when used on our Sentinel SENTIFIT®270 Analyzer or 
other automated analytical platforms. The first kit detects the total 
antibodies against the Spike RBD S1 protein, while the second detects the 
antibodies against Nucleocapsid (NC) protein. 

The new Sentinel Diagnostics assays provide the first results in about 10 
minutes. The use of Sentinel COVID-19 Anti-S1 Total Ab and COVID-19 Anti-NC 
Total Ab would help distinguish vaccinated individuals from naturally infected 
ones. The tests can be performed together on the same serum sample or 
separately to better fit with laboratory needs.
