Diagnosis
  • Obtain the relevant history of traumatic stress exposure and posttraumatic stress symptoms.
  • Evaluate patients with PTSD for other psychiatric disorders that commonly follow traumatic events.
  • Consider ordering a TSH, urine drug screen, and other tests as dictated by the clinical situation, even though laboratory tests are not absolutely indicated for healthy individuals without physical injuries. [C]
  • Consider depressive, anxiety, psychotic, and personality disorders in the psychiatric differential diagnosis of PTSD.
  • Focus the physical examination on possible medical sequelae of the traumatic event and medical illnesses that can mimic individual PTSD symptoms, even though there are no physical illnesses that cause the full spectrum of PTSD. [C]
