Highly sensitive saliva PCR test for the detection of SARS-CoV-2

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 (EUA) 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 to laboratories looking to add this test to their test menu, and to doctors looking for quality PCR testing in their practice..

Authorized kits for use in CLIA Certified Labs

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.
