This week there was a chip that was developed by researchers in Taiwan that bridged the gap between Antigen and PCR testing at-home by providing a faster but reliable results to testers. Why should we be left behind? here come the University of Washington Researchers along with Professor Barry Lutz who have developed a new test for COVID-19 that combines the speed of over-the-counter antigen tests with the accuracy of PCR tests that are processed in medical labs and hospitals.
“We designed the test to be low-cost and simple enough that it could be used anywhere,” said Barry Lutz, a UW associate professor of bioengineering and investigator with the Brotman Baty Institute for Precision Medicine. “We hope that the low cost will make high-performance testing more accessible locally and around the world.”
So how long does this test take to give results?
“This test operates at a constant temperature, so it eliminates the time to heat and cool and gives results in about 30 minutes,” said Lutz.
How does this test work?
Tests based on PCR or polymerase chain reaction are highly accurate, a key limitation is that PCR tests require dozens of cycles of heating and cooling to detect genetic material in a sample.This test developed by the UW team sidesteps this issue by relying on a PCR-like method known as RT-LAMP, which doesn’t have the same stringent temperature-cycling requirements.
