What diseases can be detected by saliva examination

Today's medicine is very advanced, and many medical devices have more powerful functions. For example, the occurrence of disease can be detected by examining saliva. So what diseases can be detected by saliva examination? Saliva is also one of the body's body fluids and can be used to check the body's digestive system. In particular, special molecules in it called biomarkers can be used to predict the location of tooth decay and may even be used to detect HIV in the future.

By testing these substances in saliva, it is also possible to detect whether you have many diseases, including cancer.

The report pointed out that the oral cavity is a window into the human health. Saliva and oral fluids have gradually become the basis for hospitals to examine physical conditions through laboratory tests. Compared with blood and urine tests, saliva tests are gradually gaining popularity because they are not only reliable but also do not cause any discomfort to the person being tested. At the same time, saliva is easier to collect when conducting tests, which is particularly useful when doing toxicology tests. Saliva is tested primarily to look for specific molecules called "biomarkers" that can indicate the presence of a disease. Certain substances in saliva can be used to "predict" how many cavities a person will have and even predict the location of the cavities. Currently, dental health can be checked by testing saliva. Another development direction of saliva testing is to detect AIDS.

This technology will soon be available in hospitals and clinics. Using saliva tests, it only takes a few seconds to detect whether a person is infected with HIV, while conventional blood tests often require waiting for several hours or even days. The cost of saliva testing for HIV is much lower than blood testing. Although saliva testing technology has made significant progress, Edward, a spokesman for the U.S. Department of Health and Human Services. Cohen said saliva cannot currently be used as the primary basis for testing. For this reason, some scientists believe that the medical community should quickly discuss whether oral secretions can be used as a basis for medical testing.
