BARDA expands partnership with DiaSorin SpA to develop automated antigen detection assay for acute COVID-19

About Image

BARDA is expanding its existing partnership with DiaSorin SpA on the development of a COVID-19 immunoassay. This new test detects the presence of SARS-CoV-2 in nasal swabs or nasopharyngeal swabs to diagnose acute COVID-19 disease.

DiaSorin intends to develop, validate, manufacture, market, and obtain regulatory authorization in the United States and worldwide for this new, fully automated, chemiluminescent, antigen assay for the qualitative detection of the SARS-CoV-2 virus using nasal swabs or nasopharyngeal swabs. This assay will allow testing of nasal swabs in addition to traditional nasopharyngeal swabs, thereby expanding the utility of the assay by simplifying collection and enhancing patient comfort and safety.

This test is being designed to determine if an individual is experiencing acute SARS-CoV-2 infection by detecting the presence of the N protein of the virus in multiple clinical samples. The LIAISON XL platform allows laboratories to process up to 136 patient samples per hour, with a minimum level of intervention required by laboratory operators. Individual lab-based test results can reach healthcare providers in under three hours.
