Assuming that the human body has identified COVID-19 and has the corresponding symptoms, nucleic acid is found to be 100% positive. Negative is impossible?
If the patient has positive symptoms of the new virus, it must be a bad phenomenon, indicating that the patient is infected with the new virus, which is still relatively destructive to the human body, and it is difficult to treat. We must be actively hospitalized. If COVID-19 is infected with nucleic acid testing, if there is no error, the result is positive. But sometimes there are errors, there will be false positives or false negatives. It needs to be tested again.
Novel coronavirus pneumonia is a positive condition for COVID-19 infection, according to the question of consultation. Nucleic acid detection is the gold standard for diagnosing New Coronavirus infection. As long as you get the virus. Nucleic acid must be positive. Unless the sample collection is unqualified, there is a problem with the quality of the test reagent.
If the body is infected with COVID-19, its detection of nucleic acids must be positive. It can't be negative. As long as the presence of COVID-19 infection in the body, there will be positive results of nucleic acid detection, so the result of nucleic acid detection is the gold standard to diagnose whether it is infected with COVID-19.
