He was hospitalized, testing negative for coronavirus several times before eventually receiving a positive result. On Jan. 30 the doctor posted:"Today nucleic acid testing came back with a positive result, the dust has settled, finally diagnosed," according to the BBC. Dr. Wenliang passed away on February 7 in Wuhan, the epicenter of the outbreak.

What is the nucleic acid test (NAT)? Blood Basics

The nucleic acid test (NAT) system can detect the presence of bacteria and viruses (e.g. human immunodeficiency virus (HIV) and hepatitis C virus (HCV)) in blood using a semi-automated system and further ensures the safety of blood products, including fresh frozen plasma, red cells, and platelets by permitting earlier detection of infections in donors.
