Any blood tests or regular tests to diagnose generalized anxiety disorder or depression? I had my serotonin levels checked, and they were at 132.

In brief: Unfortunately,
Even checking serum serotonin levels doesn't always tell us what is going on in the brain because of something called the blood brain barrier.
This is a barrier that lets some things in or out but not other things. And serotonin is only one of the neurotransmitters implicated in depression. So no, there is no reliable tests for diagnosing mental illnesses yet.

In brief: Lab tests for anxiet
Most doctor's diagnose anxiety and or depression per history as well as filling out a questionnaire.
Yes serotonin may be involved but this is most likely an expensive unneeded lab test that is rarely used.

In brief: No
There are no current blood tests that have been validated for anxiety and depression.
Blood levels of neurotransmitters like serotonin are of no help, because they don't tell you how much and where serotonin is acting in the brain. The good news is that the diagnosis and a plan of treatment can be easily made by a psychiatrist or other experienced clinician by a good history and interview.
