Antigen testing is generally referred to as a new crown antigen test, and colds are generally referred to as upper respiratory tract infections, which usually do not result in two bars on a new crown antigen test.
For patients with common upper respiratory tract infections, there is no need to worry about the two bars on the new coronavirus antigen test. However, some patients with novel coronavirus pneumonia may have symptoms similar to those of upper respiratory tract infections, such as fever, cough, and malaise, and these patients may show two bars on the new coronavirus antigen test and need to be taken seriously.
In normal people, a single bar on the new coronavirus test means that the body is not infected with the new coronavirus. If there are two bars on the test, it is an abnormal phenomenon, which means that the body is infected with the new coronavirus. However, some patients are prone to false-positive results and need to combine with other tests to confirm the diagnosis.
It is recommended that people with abnormal results of the new coronavirus antigen test should report to the community in order to determine whether they are suffering from new coronavirus pneumonia.
Tip: In this article, “new coronavirus pneumonia” and “new coronavirus pneumonia” were renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
