BARDA expands partnership with DiaSorin Inc to develop an enhanced IgG assay for determining COVID-19 patient exposure and immune status

About Image

BARDA has expanded its existing partnership with DiaSorin Inc. on the development of a COVID-19 immunoassay. The test detects the presence of antibodies to SARS-CoV-2 in human serum and plasma of a recently infected individual.

This test could help determine if someone lacks the antibodies against SARS-CoV-2 spike protein. If a COVID-19 vaccine receives approval or authorization from the U.S. Food and Drug Administration (FDA), this DiaSorin test also could provide critical information to individuals, such as essential workers and the immune compromised regarding their current immune status.

DiaSorin intends to develop, validate, manufacture, market, and obtain regulatory authorization in the United States and worldwide for this new, fully automated, chemiluminescent, immunoassay for the semiquantitative detection of IgG class antibodies against the SARS-CoV-2 virus in human serum and plasma. This assay is intended as an aid to determining patient exposure and immune status with respect to SARS-CoV-2 virus and COVID-19 disease.
