In addition, the test can be used across various healthcare settings such as hospital emergency rooms and clinics and for at-home use by the customers.

The test could potentially reduce the waiting period to receive test results by days as it does not need to be sent to off-site laboratories for analysis.

If FDA authorises emergency use of the device, NOWDiagnostics’ subsidiary C19 Development will initiate distribution of the test for use in CLIA-certified labs in various healthcare settings such as clinics and hospital emergency rooms.

Clinical trials for the over-the-counter (OTC) test use are progressing.
