Can you test for SARS-CoV-2/COVID-19?

HP Environmental now offers lab-based testing for the presence of SARS-CoV-2, the virus responsible for COVID-19, on high-touch surfaces. Testing for the presence of SARS-CoV-2 viral RNA on environmental surfaces is the most direct and definitive test for ensuring effective disinfection procedures. In critical, high-risk scenarios, and for targeted testing of areas of known contamination, appropriately validated RT-PCR methods can provide the highest level of confidence for businesses and workplaces looking to return to work while ensuring employee safety and health.

HPE uses the RT-PCR Test to examine high-touch surfaces for the presence of SARS-CoV-2 RNA and validate the efficacy of cleaning and disinfection protocols.

Please visit our COVID-19 Services page for more information on sampling and testing procedures.
