Researchers say they鈥檝e found a better way to test for COVID
Imagine being able to swab the inside of your mouth, place it in a device and quickly know whether you鈥檙e infected with COVID-19.
Johns Hopkins University researchers say they have developed a simple sensor that could quickly and accurately detect the virus that causes COVID-19 in saliva.
The sensor isn鈥檛 on the market yet, but soon could revolutionize testing, the researchers say. It could be stationed at the entrances of hospitals, airports and schools, and potentially be put into handheld and even wearable devices.
It also can detect other viruses.
In testing, the sensor was as accurate as PCR tests, the current gold standard in testing during the pandemic that requires lab processing. It also was as fast as rapid antigen tests, the at-home kits that have become prevalent but aren鈥檛 as good picking up cases.
