Using our experience in RNA analysis, Quadrant, in partnership with SUNY Upstate Medical University, developed a COVID-19 saliva test. In the Fall of 2020, our COVID-19 Saliva Test was granted Emergency Use Authorization (EAU) from the Food and Drug Administration (FDA) where it is currently referenced as the most sensitive COVID-19 saliva test on the market.  The test is available in three forms, direct sale to laboratories, through community test sites and for use at large organizations and institutions.

Authorized kits for use in CLIA Certified Labs

This simple saliva test is a qPCR test that has a Limit of Detection (LoD) of 600 NDU/mL, currently making it the most sensitive saliva test on the market in the US.  Please see Table 2C of the FDA reference panel for more information.

The Clarifi COVID-19 Saliva Test was granted Emergency Use Authorization (EUA) from the Food and Drug Administration (FDA) in September 2020, and in May 2021 the authorization was amended to include pooled testing of up to 12 samples.

Emergency use of this test is limited to authorized laboratories certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA), 42 U.S.C.  §263a, that meet requirements to perform high complexity tests.
