SARs-Cov-2 Detection in the Environment

PCR (Polymerase Chain Reaction) is a method to selectively copy ("amplify") a segment of DNA. By repeatedly duplicating the DNA, PCR can generate billions of copies from even a single starting molecule. Because only the desired segment of DNA is amplified, PCR isolates a "needle in a haystack", allowing minute quantities of pathogens to be detected and providing abundant DNA for other molecular biology techniques.

In PCR, a sample undergoes a series of heating and cooling cycles in the presence of DNA polymerase, an enzyme that replicates DNA. During every cycle, each existing copy of target DNA serves as a template for synthesizing a new copy. This chain reaction doubles the number of target DNA each cycle; an exponential amplification. PCR reactions typically involve 30 - 40 cycles which are automated by a PCR thermocycler.

PCR is widely used to diagnose infectious diseases and hereditary disorders. It is also used in veterinary diagnostics, food safety testing, water & beverage quality monitoring, and forensics. In research, PCR is used to monitor gene expression, perform gene cloning & manipulation, and prepare DNA for sequencing..

For On-Site testing, we serve all nine counties of the Greater San Francisco Bay Area, California.  

Surface Test Kits are available worldwide

Because specimen collection kit has a small form factor, it is concealable, can be deployed anywhere at anytime, and requires less than one minute to collect specimen. 

If a test confirms the presence of SARS-CoV-2, contact everyone who may have been near the infected area, and eliminate the threat with a complete disinfection service.

We recommend the following CDC guidelines: 

Exposed people having symptoms of COVID-19 should self isolate and follow CDC recommendations.

Exposed individuals, not having symptoms should remain home, practice social distancing for 14 days.

Nucleic acid test methods using Probe-based  Reverse transcription-quantitative polymerase chain reaction  (RT-qPCR) for real-time coronavirus testing is the most modern, advance technology available. 

According to the U.S. National Library of Medicine National Institutes of Health, Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) is the gold standard technique for mRNA quantification. 

Introducing RT-qPCR assays to the clinical microbiology laboratory has improved the diagnosis of infectious diseases, and as a tool to detect emerging diseases, such as additional strains of flu and coronavirus, in diagnostic tests.  

Using RT qPCR allows both the quantification and genotyping (characterization of the strain, carried out using melting curves) of a virus such as the coronavirus.

Accuracy is high as 99%, depending on testing technology and software. 

Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) is the most reliable and up to date technology for real-time coronavirus testing. 

We apply RT-qPCR technology to detect nucleic acids of infectious disease contamination on surfaces, state of the art technology.
