Chinese invent new Covid-19 test that gives result within 4 minutes

Beijing (Web Desk) – Scientists in China say they have developed a new COVID-19 test kit that returns accurate results within four minutes and is “comparable to the widely used polymerase chain reaction (PCR) test.

Just as accurate. PCR tests are widely considered to be the most accurate for the virus that causes COVID-19, but usually take several hours. Due to the rapid spread of highly transmissible Omicron variants, some countries have experienced significant backlogs as they face a large demand for testing. Chinese researchers at Fudan University in Shanghai say they have a solution. In a peer-reviewed article published Monday in the journal Nature Biomedical Engineering, the team said their sensor — which uses microelectronics to analyze genetic material from swabs — could reduce the need for time-consuming COVID labs. testing needs. “We installed electromechanical biosensors for the detection of SARS-CoV-2 into an integrated portable prototype device
Their trial involved taking samples from 33 people in Shanghai who were infected with the coronavirus, with PCR tests conducted in parallel.
