The price of the New Crown Antigen Test Kit is usually no more than $15, so please refer to your local healthcare facility for the exact price. Residents can purchase them at pharmacies and community healthcare organizations that provide outlets for their sale. However, due to the different pricing of the new crown self-test kits by different manufacturers, there is some volatility in their prices, which generally do not exceed $15. According to the requirements of the “Application Program for New Crown Virus Antigen Testing (Trial)” which has been formulated and issued, the applicable population for antigen testing mainly includes people with respiratory, fever and other symptoms and within 5 days of the onset of symptoms, people under isolation and observation, as well as community residents who have the need for antigen self-testing. If you buy the new crown antigen test kit can be used according to the relevant product instructions for self-testing, the specificity and sensitivity of the new crown antigen test kit are relatively high, but the diagnosis needs to be confirmed by nucleic acid testing.
