The presence of two bars on the New Crown Antigen test suggests that the New Crown Virus Antigen is positive, but there may be false positives. Typically, two bars or one bar will appear on self-testing with the antigen test. Two bars are red or purple bands at C and T. The presence of two bars indicates a positive antigen test result. If one bar appears at C, then the antigen test result is negative. If there is no red or purple band at C, the antigen test result is invalid. When two bars appear in the antigen test, you should report to your community, township or other relevant departments, promptly isolate yourself, avoid contact with other people, and be escorted to the hospital by a special person in charge for nucleic acid testing. If the results are negative after repeated retests, infection can be ruled out. If the nucleic acid test is found to be positive, the patient should cooperate with the doctor for active isolation and treatment.
