No laboratory tests are useful in identifying BPD. Some patients have abnormal results on dexamethasone suppression testing and with abnormal thyrotropin-releasing hormone testing; however, these findings are also present in many patients with depression. As with any thorough workup of a patient with a mood disorder, fasting glucose and thyroid function studies are usually indicated. Screening for substance abuse is often useful. Other laboratory tests are indicated, depending on the clinical presentation.

See Workup for more detail.
