Researchers Create a Protein Map of Human Spit

Ant writes "United States researchers have identified all 1,116 unique proteins found in human saliva glands. It was a discovery they said on Tuesday that could usher in a wave of convenient, spit-based diagnostic tests that could be done without the need for a single drop of blood. As many as 20 percent of the proteins found in saliva are also found in blood, said Fred Hagen, a researcher at the University of Rochester Medical Center in New York who worked on the study."

As long as you know reliability scope of test, i.e. that it gives false positives and never false negatives, test is worth it.

Simple test like this could be very effective at bringing up potential problems which can be investigated and verified by more accurate tests.

Also, you can use lots of such "unreliable" tests to build reliable model ... logic is great tool if used correctly.
