Confidence in the Classroom

Make Quadrant’s COVID-19 PCR Saliva Test part of your health & safety plan.

A simple saliva test for COVID

Unlike nasal swabs, this is a simple, non-invasive, easy-to-use, saliva collection device.  Students from kindergarten through their senior year can easily self-collect their samples.

Our saliva test accurately detects all known variants of COVID-19.

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.

Quadrant’s COVID-19 PCR Saliva Test has the lowest LOD of any saliva test currently on the market and remains effective for detecting COVID variants.

Our test has been used to at more than 100 universities, 400 primary school districts, and municipalities across the Northeast.

The collection process is quick and easy.

Stay Vigilant

Regular COVID testing helps you confidently keep your schools open and provides your students, staff, and faculty with a safe learning and working environment.
