A COVID-19 testing lab built with an air-inflated structure went into trial operation on Monday at a sports venue in Daxing District of Beijing to address the city's rising demand for nucleic acid tests after a cluster of infections were confirmed recently. The mobile Huoyan (Fire Eye) laboratory was built in two days over the weekend to accommodate 14 automated COVID-19 testing machines provided by Chinese biotech company BGI Genomics based in the city of Shenzhen, south China's Guangdong Province.
