Everything You Need Under One Roof

When you work with Quadrant Biosciences, you're working directly with the same team from distribution, to lab processing, to delivering results. 

A simple saliva test for COVID.

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 a time. Unlike nasal swabs, this is non-invasive, easy, and quick to use.

Our saliva test accurately detects Omicron, Delta, and all other known variants.

A cost-effective solution. 

The Clarifi COVID-19 test is one of only a few tests authorized by the FDA to pool individual samples for testing.

Pooled testing allows multiple samples to be run at a time, which in turn means lower costs.

Most Sensitive Saliva Test on the Market

Please see Table 2C of the FDA reference panel for more information.

An accurate test matters.

The FDA requires that manufacturers measure the sensitivity of their test against a standardized SARS-CoV-2 Reference Panel. The measure of this test sensitivity is known as the Limit of Detection (LOD). High LODs will miss more infected patients and result in more false negatives.

The Clarifi® COVID-19 Saliva Test has the lowest LOD of any saliva test currently on the market, and remains effective for COVID variants.

Quadrant's pooled saliva screening test has received FDA Emergency Use Authorization and has been used to test more than 100 universities, K-12 Schools, Nursing Homes, Municipalities and other employers.

The collection process is quick and easy.
