Our polymerase chain reaction (PCR) tests are non-invasive, saliva-based tests that provide the highest-accuracy of any test on the market. PCR is the gold-standard for detecting COVID-19 and is an excellent solution for schools, summer camps, businesses, and more.
PCR is a molecular test that analyzes genetic material (DNA). The test can detect even the smallest presence of the COVID-19 virus, allowing for significantly higher accuracy than possible with nasal-swab antigen tests.
Our process makes it easy for your staff to get tested

BEFORE BEGINNING
Test users should not eat or drink anything for at least 60 minutes before taking our saliva-based test.

For at-home test kits, users should take care to protect their samples from extreme temperatures. Don’t leave it in the car or let it freeze!


STEP 1
Users create a saliva sample using a kit-included funnel (and no swab), ensuring the sample is colorless and free of particles.


STEP 2
Test users seal the vial, place it in the provided return bag, and return the bag to collection staff (for observed testing) or the designated collection box (for unobserved testing).
