Confirmation of the new coronavirus is mainly tested in the laboratory, generally in four processes: 1, virus isolation: virus under the electron microscope through clinical specimens such as sputum or respiratory secretions, observation of virus morphology, find the 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 molecular point of view, the virus and the previous clear coronavirus for molecular DNA, RNA comparison; 4, from the molecular point of view, the virus and the previous clear coronavirus for molecular DNA, RNA comparison, the general detection is carried out in the laboratory. Clinical mainly from the patient to collect different specimens sent to the laboratory, the original to send to the CDC testing center, which takes a longer time. Now after the new coronavirus epidemic, China has manufactured many kits that can take molecular immunoassays to the clinic. Now the diagnosis can be made in 4-5 hours at the earliest, and its the result of clinical cooperation between Chinese medical workers and scientific researchers. Content source: Dr. You Lai
