The presence of a two bar after 40 minutes of the New Crown antigen test indicates a positive antigen result, although it does not necessarily mean that the person is infected with New Crown. It is possible that a false positive is due to the fact that the test has exceeded its validity time, which in turn has resulted in a non-specific result for the antigen and antibody. The Neocollins antigen test is a self-test for Neocollins, and the specific results can provide some indication of whether or not a patient is infected with the Neocollins virus. Generally, if the New Crown antigen test result shows two bars, then it means that the antigen result is positive, indicating that the patient may be infected with New Crown. However, the antigen test has a time limit of about 10 to 30 minutes. If the two bars appear 40 minutes after the new crown antigen test is performed, then it means that the effective testing time has been exceeded, and the testing environment at this time is likely to have been damaged, and therefore prone to non-specific results of antigen and antibody, so as to produce false-positive situation, and does not reflect the patient’s infection, and need to be re-tested. During antigen testing, the patient should take care to adopt the normal use of the test and try to observe the test for as long as possible in order to avoid any impact on the results. If it ends up showing two bars, then it is important to report it to the community as soon as possible and wait for a visit from a specialized doctor.
