Advice

Interpret results in the context of the full clinical picture, including longitudinal history, prior treatment response, and family history of bipolar disorder.

  • A negative screen does not rule out bipolar disorder, particularly bipolar II; if clinical suspicion remains, consider referral for structured diagnostic assessment.
