There are many types of nucleic acid tests, and the nucleic acid test we are currently referring to is the New Crown Pneumonia Nucleic Acid Test. The positive rate of the nucleic acid test will not be affected by doing the Croup test when you have a cold or cough. Nucleic acid tests are very specific and most do not mix with other cold viruses and do not affect the results of the nucleic acid test. Early symptoms of C.N.C.P. infection are similar to those of other viral infections, and most of them include fever, nasal congestion, cough, runny nose, sore throat, and loss of taste. Nucleic acid testing is a specific disease pathogen, which has a unique gene, whether it is DNA or RNA, by checking whether the patient has a unique gene fragment, and then clarify whether it is a pathogenic bacterial infection or a microbial infection. A cold is simply an infection by a virus, such as cytomegalovirus or rhinovirus. There is no crossover between the new coronaviruses and the cold viruses, which have different DNA, and the cold has no effect on the results of the nucleic acid test. In conclusion, nucleic acid testing is highly specific and colds do not affect the accuracy of the test results. Tips] In this article, “new coronavirus pneumonia” and “new coronavirus pneumonia” have been renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
