If the nucleic acid test for novel coronavirus is positive, then there is a high probability that a live virus is present in the test sample. However, if the diagnosis is further confirmed, it is necessary to do genetic sequencing of the blood specimen to compare it with the known novel coronavirus, and if it is consistent, the diagnosis will be confirmed. Therefore, patients with positive results of novel coronavirus nucleic acid should not panic, no matter what, first do a good job of isolation and protection of people around, and then do further testing, and if diagnosed, actively cooperate with health care providers for treatment.
