The New Coronavirus Nucleic Acid Test is not harmful and is a safe way to detect the new coronavirus. The nucleic acid test analyzes the sequence of the viral genes to determine whether or not a person is infected with the new coronavirus. The nucleic acid test only collects blood and respiratory secretions from the test taker, and this test is not harmful to the test taker’s body, so it is safe for testing. For some patients with throat diseases, they may experience mild pain when passing the nucleic acid test, and may also experience vomiting and nausea, etc. However, these symptoms are temporary and can be relieved after a few minutes, so there is no need to worry. For patients who are highly suspected of having novel coronavirus infection, they need to be tested through anal swabs and nasal swabs, which are not harmful to the body of the tester.
