ZEUS Scientific Announces FDA Emergency Use Authorization Approval for our ELISA SARS-CoV-2 IgG Test System


ZEUS Scientific announced today, October 7, 2020 the U.S. Food and Drug Administration (FDA) has granted Emergency Use Authorization (EUA) for its in vitro diagnostic ELISA test for the qualitative detection of IgG antibodies to the SARS-CoV-2 virus in human serum and plasma.  ZEUS has been producing and shipping the SARS-CoV-2 IgG Test System since early June 2020 and has steadily increased production capabilities to keep up with the growing demand.  Achieving EUA approval was the next step in ZEUS’s commitment to deliver superior quality COVID-19 antibody detection devices.

The ZEUS ELISA SARS-CoV-2 IgG Test System is intended for use as an aid in identifying individuals with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection. The assay utilizes a dual antigen combination of recombinant S1 receptor binding domain (RBD) viral protein and recombinant nucleoprotein for optimal performance.   Using EUA approved RT-PCR assays as the reference method, the ELISA test demonstrated 100% positive agreement. The average days between the PCR test result and the specimen draw was 15.97 days, the earliest being 3 days. A 99.1% negative agreement was demonstrated using a cohort comprised of RT-PCR negative and pre-pandemic patient specimens.  More details on the test system performance can be found on our website.

ZEUS has a long history of developing, manufacturing and delivering high quality in vitro diagnostic kits for infectious and autoimmune disease testing for over 40 years.  With over 125 FDA cleared assays in our menu, we welcome you to explore our ELISA menu to see how ZEUS is capable of helping your lab today accommodate increased immunoassay testing demand.

The SARS-CoV-2 IgG Test System assay follows ZEUS’s universal ELISA assay protocol. This protocol offers a high degree of flexibility with incubation times (20-30 minutes for sample incubation and conjugate incubation, 10-15 minutes for TMB substrate incubation) allowing for simple, efficient, and flexible automation programming on open pipetting systems.  ZEUS has received EUA approval to run the ZEUS ELISA SARS-SoV-2 IgG Test System manually or using the Dynex Agility® Automated ELISA System. The Agility offers high throughput and takes advantage of the SmartKit™ Gold packaging, providing the ability to fully automate the procedure from sample to result in a throughput meeting all laboratory requirements.  The new Test System also includes our proprietary SAVe Diluent, a unique component which changes color when serum is added ensuring no well is missed!
