What are the tests for schizoaffective disorder?

Clinical diagnosis: Schizoaffective disorder is a clinical diagnosis; there are no lab tests. One is looking for a pattern of disturbances in both mood (depression, mania, or a mixture of both) and impaired reality testing (hallucinations, delusions, problems with thought processes). Both types of symptoms need to be prominent over time.

Schizoaffective: Schizoaffective disorder is an extremely serious illness that can be thought of as a combination of schizophrenic (psychosis) and bipolar disorder (the old term being manic depression) with involves extreme mood swings. There are really no "tests" to determine such a diagnosis. Rather, a full evaluation by a seasoned psychiatrist is the best way to go.
