Neocoronavirus antigen generally refers to the Neocoronavirus antigen test, and oranges do not normally make the Neocoronavirus antigen test result positive. The Neocoronavirus antigen test is a home-based self-assessment for Neocoronavirus infection, with a negative result providing a preliminary diagnosis of non-infection and a positive result providing a preliminary diagnosis of Neocoronavirus infection. Normally, eating oranges will not cause a positive test result, and other foods will not affect the test result, so there is no need to worry too much. False-positive or positive results may occur if the test is not performed according to the instructions, or if the test kit is outdated or not up to standard. When the result of Neocoronavirus antigen test is abnormal, you can seek medical advice for further nucleic acid test, lung CT, etc. to clarify whether you are infected with Neocoronavirus. It is recommended to strengthen personal protective measures on a daily basis and avoid close contact with others. Persons suspected to be infected with novel coronavirus should seek treatment at designated hospitals or report to the community or be isolated at home as early as possible to prevent further spread of the novel coronavirus.
