Do the tests for panic disorders work ok?

Not sure what u mean: No tests i know of--dx made by history & exclusion--if you give sodium lactate i'v to a person who is predisposed you can cause them to have a panic attack.

What tests??: I can diagnose a panic attack by witnessing a patient have one with history provided or by a classic history alone. Medical causes sometimes need to be ruled out. I don't know of any specific tests for panic disorder.
