Nucleic acid qualitative testing refers to a detection method that identifies the presence of a specific pathogen by detecting its unique nucleic acid sequences in a sample. This type of testing is commonly used for diagnosing infectious diseases. The process typically involves collecting patient samples (such as nasopharyngeal swabs, saliva, blood, etc.), extracting nucleic acids from the samples, and then using specific techniques (such as PCR) to amplify and detect the pathogen's nucleic acid sequences. If the specific nucleic acid sequence in the sample matches the DNA or RNA of the target pathogen, the result is positive, indicating that the patient may be infected with the relevant pathogen.
