The evaluation of bipolar disorder begins with a medical history, physical examination and a psychiatric evaluation.

Usually, tests are not required to make the diagnosis of bipolar disorder. However, tests may be required to exclude conditions that cause similar symptoms.

Tests that may be used to evaluate symptoms of bipolar disorder include:

• Blood tests
• Blood toxicology
• Thyroid profile
• EEG
• CT scanning of the brain
• MRI scan of the brain
