BEIJING — China has asked local authorities to further lower the price of COVID-19 nucleic acid tests to no more than 28 yuan (about $4.4) per person for a single test.

The price for testing a group of 10 people should be no more than eight yuan per person, according to a notice issued by the National Healthcare Security Administration and the State Council joint prevention and control mechanism against COVID-19.

The document requires all provincial-level regions to complete the price adjustment by at least the end of April.
