Criterion employs a rapid detection method called RT-qPCR. This is the same test as specified by the CDC for the detection of SARS-CoV-2 in humans, and is used to detect SARS-CoV-2 in both surface and air samples. However, Criterion’s lab method is NOT FOR DIAGNOSTIC USE.

Criterion reports results as either “Detected” or “Not Detected” for the 2 indicators of the SARS-CoV-2 (N1 and N2). Both indicators detect the N gene of the SARS-CoV-2 virus. A “Detected” results in either of these 2 indicators, SARS-CoV-2 is present.

CLEANING EFFICACY TESTING SERVICES

As a more economical alternative to SARS-CoV-2 surface testing, Criterion offers Cleaning Efficacy Testing Services.

This service tests surfaces for culturable fungi and bacteria. If the results are negative, you can assume a surface was effectively disinfected if a a broad spectrum germicide was used.

If you collect your own samples, please call. We can provide sampling media for surface testing.
