A new crown antigen test result of two bars and a negative nucleic acid test result is not negative and is considered to be infected.
New Crown antigen test result with two bars is positive, according to the “New Crown Virus Antigen Test Application Program (for Trial Implementation)” issued by the National Health and Wellness Commission, patients with a positive antigen test and a negative nucleic acid test are regarded as being infected with the New Crown Virus, and measures such as centralized isolation should be taken, close observation should be carried out, and nucleic acid tests should be performed on them consecutively. If the diagnosis is confirmed, appropriate measures will need to be taken.
It should be noted that there is a possibility of false positives in the antigen test, mostly due to malpractice, but even false positives are treated as new coronavirus infections. Centralized isolation measures should be taken and repeated nucleic acid tests should be performed, and if the tests are not negative, the patient can be excluded from the neo-coronavirus infection.
The chance of false positive or false negative nucleic acid test is small, but there is a possibility that multiple nucleic acid tests are needed. Residents should cooperate actively, and isolation is required if the diagnosis is confirmed.
A two-bar New Crown antigen test result should be followed up by a hospital visit and active treatment under a doctor’s supervision after a clear diagnosis is made, so as to avoid delaying the condition.
