The result of the New Crown nucleic acid test mainly depends on whether the report card result is positive or negative. Generally, in order to prevent the spread of the New Crown virus, professional testing organizations mainly collect nasal swabs or pharyngeal swabs from the examinees and test the samples for both IgM and IgG antibodies. After the test, if the person is not infected with the new coronavirus, the result of the nucleic acid test is negative. For those who are infected with the new coronavirus, the nucleic acid test results are positive. Of course, during the testing process, there are cases of false positive and false negative test results due to sample contamination, technical influence, virus incubation period, etc. Professional testing organizations will isolate or re-test according to the actual situation. Therefore, during the prevention and control of the epidemic, we should actively cooperate with nucleic acid testing to prevent leakage of diagnosis.
