Blood test for anxiety

This company claims:

A new technique that can accurately diagnose anxiety disorders by performing a simple blood test, was developed at the Hebrew University in Jerusalem. The researchers hope that the anxiety blood test will soon make its way into hospitals and E.R. rooms and give doctors and psychiatrists a quick and precise tool for examining, and eventually treating, these disorders. The team has recently started work on another common illness ? depression. They hope to find a way to diagnose and finally treat the millions who suffer from this illness as well.

It is probably no worse than using ink blots, as some psychologists still use Rorschach tests.
