Answer

No laboratory tests are useful in identifying borderline personality disorder (BPD). Some BPD patients have abnormal results with dexamethasone suppression testing and with 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. Other laboratory tests are indicated, depending on the clinical presentation.
