Cold can do nucleic acid test need to be analyzed according to the specific situation, can not be generalized, such as the new type of coronary pneumonia, the cold does not affect the nucleic acid test results, so it can be done, but may be due to the different testing methods will lead to patient discomfort. Nucleic acid is the storage and transmission of genetic information, including DNA and RNA two categories, that is, the genetic sequence of pathogens, nucleic acid testing is mainly targeted detection of pathogens, and colds may be caused by bacterial and viral infections, which cause colds, including adenoviruses, influenza viruses, etc. Colds carry the virus is not necessarily the same as that carried by the virus. As in the case of the new crown virus nucleic acid test, both the new crown infection and the cold will have symptoms such as fever and malaise, but the genetic sequences of the viruses carried by the new crown and the cold are different, and the new crown nucleic acid test will not affect the test results when the cold is present.
