Nucleic acid testing is not carcinogenic. Nucleic acid is a general term for deoxyribonucleic acid and ribonucleic acid (i.e., DNA and RNA collectively), which is the most basic genetic material of life. Since each species has different genetic material, nucleic acid testing helps determine the properties of the species. Particularly in the case of pathogens that cause disease in humans, nucleic acid testing can help to identify the infecting agent. The technology of nucleic acid detection of pathogens mainly relies on the main procedures of sampling, nucleic acid extraction, instrumental detection, and manual judgment. 1. Sampling: With the help of respiratory specimens, blood or fecal specimens collected from patients. 2. Nucleic acid extraction: With the help of various kits to extract the genetic material of pathogens contained in the collected specimens. 3. Instrumental detection: using professional instruments, setting parameters and adding various primers to carry out relevant experiments. 4. Manual judgment: According to the experimental results to determine whether there is a certain pathogen. Therefore, nucleic acid testing does not have any carcinogenic risk to human body and can be carried out with peace of mind.
