Confirmation of the new coronavirus is mainly tested in the laboratory, as follows: 1, virus isolation: virus under the electron microscope through clinical specimens such as sputum or respiratory secretions, observation of virus morphology, find virus particles; 2, virus culture and isolation, generally in blood or secretions, but also fluorescence detection; 3, viral pathogenesis isolation, antigen antibody detection; 4, from the perspective of molecular biology, the virus and the previous clear coronavirus for molecular DNA, RNA comparison, general testing is carried out in the laboratory.
