Positive antigen test usually refers to the case of positive antigen test for novel coronavirus. Antigen test is mostly used in the early stage of infection, which is easy and fast to operate, but the accuracy is lower compared with nucleic acid test. Therefore, when the antigen test is positive, it should be reported to the community, township and other relevant departments, prohibited from going out, prohibited from contacting others, and escorted to a hospital for nucleic acid testing by a person in charge. Antigen testing is not a substitute for nucleic acid testing and cannot be used to confirm the diagnosis of novel coronavirus infection. Regardless of the presence or absence of symptoms, persons who test positive for antigens should be reported promptly and go to the appropriate hospital with a fever clinic for nucleic acid testing. In addition, the collection tubes, test cards and other items used by those who test positive for antigen should be transferred to the hospital for uniform disposal to avoid virus leakage and transmission. If the results of the nucleic acid test are negative, you should not take it lightly and retest under the guidance of your doctor. During this period, you should listen to the arrangements of the responsible staff and medical personnel and cooperate with them to avoid delaying your condition and causing adverse effects on others.
