Clarifi COVID-19 Pooled (Group) Test

Clarifi COVID-19 Pooled (Group) Test

Introducing the Clarifi COVID-19 Pooled Test Kit.

What is Pooled testing?

Pooled testing combines the ease and simplicity of our saliva test with the accuracy of PCR testing to allow group testing of up to 12 people at one time.

Our pooled testing process utilizes our Clarifi COVID-19 test kit, which received FDA EUA on September 22, 2020 and updated on May 6, 2021.

Using the FDA Reference Panel, this test demonstrated a Limit of Detection (LOD) of as few as 600 copies of the SARS-CoV-2 virus per mL; this LOD currently places the Clarifi COVID-19 Test Kit as the most sensitive saliva test available for sale in the United States (see Table 2C).

Tests with lower LODs are better able to detect infections at the earliest stages when individuals may be infectious but have not developed symptoms.

Pooled Testing

Why use pooled testing?

Pooled testing allows for quick and cost-effective testing of large populations.  Each pool can test up to 12 individuals.

Because the individual saliva swabs are retained, immediate reflex testing of individual samples can be done if a pool comes back with a positive result.

Pooled testing has been ongoing throughout New York State at SUNY Universities and K-12 schools.  It is a great option for schools, universities, employers and other organizations to conduct large-scale, cost-effective testing.
