COVID-19 Testing is Now Available!

COVID-19 testing is now available to accurately detect whether the virus is present on a surface. The presence or absence of the viral genetic material on environmental surfaces are now being analyzed by several laboratories for SARS-Covid-19 using a process referred to as polymerase chain reaction (PCR) genetic testing for COVID-19 regarding disinfection.

Surface Testing Methodology and Protocol for COVID-19 Inspection and Testing

GuziWest has developed a surface testing swab sampling methodology and protocol for COVID-19 Inspection/Testing based upon information published by the CDC and World Health Organization (WHO).  In conjunction with a CA-certified laboratory performing Covid-19 PCR testing, we’re able to offer rapid information on the safety of your working surfaces and the potential presence of COVID-19 virus within your office or production facility.

Any test method to determine complete disinfection of the virus needs to be evaluated carefully. Find out how that can be done here.

Evaluating COVID-19 Test Methods

Recent studies have shown viable coronavirus can be detected up to three hours later in the air, up to four hours on copper, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel. Cleaning of visibly dirty surfaces followed by disinfection is best practice for prevention of COVID-19 and other viral respiratory illnesses in your household and in community settings. Regular household cleaners are effective, including bleach solutions and alcohol solutions of at least 70% alcohol. The EPA provides a list of disinfectants effective against COVID-19.  Depending on the length of time in the facility and the areas traversed by the confirmed COVID-19 case, consideration may be given to using
a professional cleaning/disinfection service and extreme measures such as ozonation, UV disinfection, and/or ULV fogging.

Coronavirus Surface Disinfection

With the recent pandemic, there are a few different types of tests and technologies for surfaces and buildings being marketed regarding the verification of disinfection for the coronavirus.  Guzi-West staff are currently evaluating these, however at this time don’t feel that the available tests can absolutely determine the total disinfection of the virus from any given surface.

Any test method to determine complete disinfection of the virus needs to be evaluated carefully.  Will the test method directly measure the presence of the coronavirus? Will the test be measuring for simple proteins which may be already present in the environment?  Will it be measuring for DNA or RNA sequences that may relate to the virus, and can it differentiate between a live sample and dead sample that has been deactivated by sanitation? The best testing methods will actually culture and grow organisms from the surfaces and can determine if potential virus particles have been fully disinfected.
