According to a report in Reuters, U.S. researchers were able to identify 1,116 unique proteins found in human saliva glands. According to Fred Hagen, a researcher at the University of Rochester Medical Center in New York, around 20 percent of the proteins found in saliva are also found in the blood. This could perhaps lead to an easy diagnostic test without the use of painful needle injection and without a single drop of blood.
If this would be viable, it would create many clinical implications in the area of diagnostics since this would allow using the saliva to diagnose cancer, heart disease, diabetes, and many more health conditions.
In fact on another study, there is also the possibility of using the saliva to determine if the person is suffering from heart attack or just merely a simple case of heartburn.
Though the probability of using the saliva for such test is still not that close, it looks promising and all that is needed is to have a comprehensive understanding of the saliva proteome.
