A cold will not affect the results of the nucleic acid test for Novel Coronavirus. The nucleic acid test for novel coronaviruses determines their specific nucleic acid sequences, which have high specificity and accuracy for confirming the diagnosis. Colds are infected by other types of viruses, such as rhinoviruses, respiratory syncytial viruses, influenza viruses, etc., whose nucleic acid sequences are different from those of the novel coronaviruses, and therefore do not affect the test results. Therefore, it is possible to perform nucleic acid testing when you have a cold. What affects the results of nucleic acid testing are often factors such as irregular specimen collection, too long a time from collection to testing, and errors in the process of manual extraction of nucleic acids.
