There is no test that can make a schizophrenia diagnosis. People with schizophrenia usually come to the attention of a mental health professional after others see them acting strangely.
Doctors make a diagnosis through interviews with the patient as well as with friends and family members.
Psychiatrists have the most experience with diagnosing schizophrenia. A psychiatrist or other licensed mental health professional should be involved in making a schizophrenia diagnosis whenever possible.

There are several types of schizophrenia. The most common is paranoid schizophrenia, which causes people to have frightening
thoughts, believe that people or forces are trying to harm them, and hear
voices. Some people think that schizophrenia is the same as a "split
personality" (dissociative identity disorder), but that is a
different mental health problem.

What are the symptoms?
Symptoms of schizophrenia
Negative symptoms. "Negative" doesn't
mean "bad." Negative symptoms are things that are "lost" from your personality
or how you experience life. You may:
Not care about things.
Have no interest or drive to do things.
take care of yourself, such as not bathing or not eating regularly.
Find it hard to say how you feel.
Become angry with strangers for no
reason and react to others in other harmful ways.
Positive symptoms. "Positive" doesn't mean "good." Positive
symptoms are things "added" or "new" to your personality or how you experience
life. They include:
Thoughts and speech that are confusing.
Cognitive symptoms. These symptoms have to do with how you think. They often aren't
obvious to you or others. They can include:
Not being able to understand things well enough to make decisions.
Having trouble talking clearly to others.
Symptoms usually start when you are a
teen or a young adult, but they may start later in life. They may appear
suddenly or may develop slowly. You may not be aware of your symptoms.
Negative symptoms usually appear first. They may be hard to recognize as
schizophrenia, because they are similar to symptoms of other problems, such as
depression. Positive symptoms can start days, months,
or years after the negative symptoms.
Early signs of
schizophrenia may include doing worse in school, thinking that people are
trying to harm you, or having changes in your personality, such as not wanting
to see people.
These signs don't mean you have schizophrenia. But
if you notice these signs, see a doctor.
