The new crown antigen test can be viewed by looking at the “C” and “T” bands. If both “C” and “T” show red or purple bands, it means that the result of the new crown antigen is positive, and it is necessary to isolate and do the new crown nucleic acid test in time; if “C” shows red or purple bands and “T” shows red or purple bands, it means that the result of the new crown antigen is positive, and it is necessary to isolate and do the new crown nucleic acid test in time. If “C” shows a red or purple band and “T” does not show a band, it means that the new crown antigen result is negative, if “C” does not show a red or purple band, it proves that the test result is invalid. The new crown antigen test is fast and easy to perform, so you don’t need to rely on a professional to perform the test, you just need to collect a sample on your own. The results will be available in about 15 minutes. It is important to note that antigen testing can sometimes be interfered with and false positives can occur, so antigen testing cannot completely replace nucleic acid testing. People are advised to take antigen test regularly and seek medical advice if there is any abnormality.
