DNA barcode may speed COVID-19 testing

Professor Paul Hebert’s team at the University of Guelph that developed bar coding for species Is adapting the technology to test for COVID-19.

The team’s approach promises to be much faster and cheaper than current tests which cost about $40 to $100 each and take days to produce results.

Their approach involves identifying a single gene specific to COVID-19, then screening swabs to determine whether that gene is present.
Their approach can do batches at a time, amounting to thousands per day. That speeds up the testing process and reduces the cost to about $1 per sample.

Herbert told CBC that processing thousands of samples daily is key to monitoring the spread of the COVID-19 and could allow for more informed decision making on the enforcement and relaxation of lockdowns. 

"For example, the safe reopening of schools and workplaces will require upwards of 100,000 tests a week," he said.
