Saliva testing, a non-invasive sampling method, is attracting attention in the medical field due to its convenience and speed.
Saliva contains various biomarkers such as DNA, RNA, proteins, and metabolites, reflecting a person's health status. Analysis of specific proteins in saliva can detect diseases like oral cancer early.
Moreover, viral diseases like HIV and influenza can be diagnosed by detecting viral nucleic acids in saliva. In addition to disease diagnosis, saliva testing demonstrates unique advantages in genetic disease screening and drug monitoring. For instance, genetic disease screening can be non-invasively conducted by analyzing DNA variations in saliva, providing a convenient and harmless approach for patients.
Saliva, as a novel biological sample, shows great potential in disease diagnosis. With advancing research and innovation, we have reason to believe that saliva testing will play a bigger role in the future of medical field.
