Utilizing flow cytometry and intracellular cytokine staining, SARS-CoV-2 inSIGHT™ testing could be an important tool for evaluating immunological memory to the SARS-CoV-2 virus, and even indicate a level of protection from further infection.

SARS-CoV-2 inSIGHT™ testing joins a robust menu of COVID-19 testing, including the recently-launched cPASS™ Coronavirus SARS-CoV-2 Neutralizing Antibody test. When used in combination with the Neutralizing Antibody test, results from the tests could help physicians evaluate two areas of our adaptive immune system that can indicate immunity. When neutralizing antibody response begins to diminish months after exposure to the virus or vaccine, the presence of T cell immunity may signify long-term immunity.

A leader in infectious disease testing for over 35 years, Viracor has launched molecular and serological tests to aid in the evaluation of naturally infected or vaccinated individuals. To see the full list of testing, visit https://www.eurofins-viracor.com/clinical/our-testing/covid-19/. Furthermore, Viracor's SARS-CoV-2 RT-PCR assay offers the best sensitivity of the 117 laboratories that have submitted results to FDA's SARS-CoV-2 Reference Panel, with a limit of detection of 180 NAAT Detectable Units/mL^1,2.

¹ This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration. This test has been authorized by FDA under an EUA for use by authorized laboratories. This test has been authorized only for the detection of RNA from SARS-CoV-2 virus and diagnosis of SARS-CoV-2 virus infection, not for any other viruses or pathogens. This test is only authorized for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of in vitro diagnostic tests for detection of SARS-CoV-2 virus and/or diagnosis of SARS-CoV-2 virus infection under section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the authorization is terminated or revoked sooner.
