SARS-CoV-2 (COVID-19) virus Surface Testing

Barclay Assessment Services, L.L.C. is now providing surface testing to confirm the presence/absence of the SARS-CoV-2 (COVID-19) virus on surfaces utilizing quantitative RT-PCR technology.

Recent studies suggest that the SARS-CoV-2 virus may remain viable and infective on surfaces for hours to days, depending on the surface’s material type (fabric, tile, steel, etc.).

Thorough cleaning and disinfection of frequently touched surfaces are recommended by the U.S. Centers for Disease Control and Prevention (CDC) and believed to be essential in preventing the spread of infection. The presence or absence of the viral genetic material on environmental surfaces can now be directly tested with a molecular-based test used to demonstrate effectiveness of cleaning protocols.

This method is specified by the CDC and authorized by the U.S. Food and Drug Administration (FDA) for clinical COVID-19 diagnostics.

Please not that since the human RNAse P gene is not analyzed in the collected sample, the RT-qPCR test can only be used for environmental testing on surfaces; not for processing patient SARS-CoV-2 specimens.
