Individuals may see a mental health professional to take diagnostic testing to determine a proper diagnosis. While there are only tests, it is important to consult a professional due to overlapping criteria for diagnosis between the different bipolar disorders and other mental health diagnosis' under the DSM -5. Be sure to track your moods and symptoms, as this may help with determining whether or not bipolar is a possibility, or if symptoms could be explained by other similar conditions such as Borderline Personality Disorder.
