How is Bipolar Disorder Diagnosed?

A doctor or psychiatrist diagnoses bipolar disorder based on specific criteria that have to do with the type and severity of symptoms. There is no laboratory test that can diagnose bipolar disorder.

Diagnosis usually involves two steps. The first step involves an evaluation of the patient’s condition and history  (which is when a mental health expert, such as a psychiatrist, will evaluate a patient’s condition and history to diagnose bipolar disorder): By asking questions about their symptoms, family history, and other factors:including a discussion of any symptoms they may have experienced. A patient’s friends and family may be involved in this process, especially for answering questions about possible manic episodes.

If this first step indicates that a patient likely has bipolar disorder, then the second step is to make sure that the symptoms are not being caused by any other condition. This can include a review of a patient’s prescription medications as well as blood tests, urinalysis, and checking thyroid function.
