In brief: Clinical exam
Schizophrenia is diagnosed by a medical expert, like a psychiatrist, who interviews the individual to identify specific thinking patterns and symptoms.
It is not diagnosed until symptoms have been present for many months, because symptoms of psychosis can improve on their own. The primary symptoms to look for are evidence of bizarre delusions or hallucinations.

In brief: By a psychiatrist
Schizophrenia is a dramatic illness with devastating consequences.
A thorough psychiatric evaluation which involves family history, medical, past and present history as well as drug abuse history is taken in to consideration. Initial work up may include blood tests and a ct scan of the brain to rule out other causes of psychosis. It is hard for untrained eyes to tell mild psychotic episodes.
