The per-specimen supply cost of our SARS-CoV-2 whole genome sequencing method was estimated to be $33.8. When it comes to coronavirus, genome sequencing allows not only testing for SARS-CoV-2, but also goes beyond classifying the virus and its lineage. "The analogy that I like to use is that when we sequenced the genome, the genome for a patient's COVID-19 is really like a book and the letters and the words and the paragraphs in that book are what tell the virus, how to make more virus, how to infect cells, how to do all the things that it does. Accelerated integration of genome sequencing into the practices of the global health community is required if .

Christopher Tufton, says a Genome Sequencing machine to test for new coronavirus (COVID-19) variants is expected to arrive in the island over the next two to three weeks. PCR only works on DNA, and the COVID-19 virus uses RNA as its genetic code. One of the diagnostic tests for COVID-19 is the polymerase chain reaction or PCR test, which can identify about three locations within the genome of the virus, said Dr. Phil Febbo, chief medical officer for Illumina, a San Diego-based company that develops genomic sequencing technologies.
