"Breathing to test the new crown" becomes possible

There is no need to "poke the throat" or "poke the nostrils" or wait 24 hours.

A paper recently published online in the international academic journal "Journal of Respiratory Research" shows that the team of Professor Maosheng from the School of Environment of Peking University cooperated with teams such as the Chaoyang District Center for Disease Control and Prevention of Beijing to integrate exhaled breath sampling, gas chromatography-ion migration Spectral detection and machine learning models have developed a non-invasive exhaled breath volatile organic compound fingerprint screening system for COVID-19 infection.

Yaosheng explained the principle behind the technology to a reporter from Science and Technology Daily: Due to changes in energy consumption, the chemical composition of the breath exhaled by people infected with the new crown will be different

There is no need for any test reagents in the test.

"Experiments have proven that this method is effective

Yao Maosheng added that the new crown nucleic acid test sometimes has the problem of "false negative"

According to international media reports, since 2020, scientific researchers in Singapore, Japan, Indonesia and other countries have developed the "New Breath Test" technology

"At the beginning of the outbreak of the new crown epidemic, we were developing this technology
