At present, the New Crown Pneumonia Virus can be self-tested by the colloidal gold method, i.e. antigen detection, while nucleic acid testing still has to be done at the hospital. The self-assessment for neocoronavirus antigen is suitable for people who have symptoms such as fever and respiratory tract infection within 5 days. The general operation is to use a sampling swab into the nostrils about 1.5 centimeters against the nasal mucosa and rotate the sample, and then put the sampling swab into the extraction tube and take a number of drops of the sample into the test card to get the result. A positive result is obtained if there is a bar at all CT sites, a negative result if there is a bar at C only, and an invalid result if there is no bar at C. Although the test can be self-tested by the tester with the Neocollin antigen kit, it is still not as accurate as the nucleic acid test, which is still the basis for a definitive diagnosis of Neocollin virus. If you have symptoms related to Neocollins, it is best to go to the hospital for nucleic acid testing, gather less, wash your hands more, and get vaccinated against Neocollins.
