USA – Thermo Fisher Scientific has developed a rapid environmental test that can detect SARS-CoV-2 pathogens in the air faster than ever before.

The US – based research firm unveiled the Renvo rapid PCR test, which detected airborne pathogens in just 30 minutes when used with samples collected from the company’s AerosolSense Sampler.

According to the company, it is intended for environmental surveillance in community locations such as schools, businesses, healthcare facilities, and government buildings, and it uses nucleic acid amplification to detect in-air SARS-CoV-2 viral RNA.

The technology will allow institutions to perform Covid-19 testing on-site, eliminating the need for specialized training or sending samples to a lab for analysis.

Previously, the company’s AerosolSense Sampler produced results in four to twenty-four hours. Now, proprietary OSCAR PCR technology has helped cut thermocycling time in half, resulting in results in 30 minutes instead.

There is a clear need for heightened surveillance and testing of indoor air quality.”

Promising highly accurate detection of SARS-CoV-2 pathogens through indoor air sampling can produce accurate results in just 30 minutes.

This is a significant improvement over previous models’ four to 24-hour testing turnaround time.

The faster response time could lead to more timely decisions and the strengthening of risk mitigation strategies for communal locations and facilities.

Overall, Thermo Fisher’s response to Covid-19 has included other PCR testing solutions, virus and epidemiological research, vaccine development, and lab products.

Other COVID-19 tests, such as those from Roche Holding AG and Abbott Laboratories, can be used to diagnose positive cases of COVID-19.

The Renvo rapid PCR test does not require any specialized training, making it simple to use. To perform the test, users insert a Renvo cassette into the Renvo dock, which then tests air samples using a fluid extraction process known as elution.

Finally, before delivering results, the machine applies controlled voltage signals to various cassette heaters.

The sampling technology is currently approved by the US FDA for emergency use.
