Laboratory Studies
- Toxicology screen: Substance abuse is common in many personality disorders, and intoxication can lead patients to present with some features of personality disorders.

Other Tests
Psychological testing may support or direct the clinical diagnosis.[3, 2]
- The Minnesota Multiphasic Personality Inventory (MMPI) is the best-known psychological test. The Eysenck Personality Inventory and the Personality Diagnostic Questionnaire are also used. None of these has been reliably validated against DSM-IV-TR diagnoses.
- The Structured Clinical Interview for DSM-IV-TR for Axis II Disorders (SCID-II) can also be used to aid in diagnosis.
