PTSD is a clinical diagnosis; there are no laboratory tests or brain-imaging studies currently used in clinical practice to diagnose PTSD. Brain imaging studies are under way to learn more about the brain in the PTSD condition, but these are not used in everyday medical practice. A physical exam and some blood tests may be necessary to rule out medical conditions that may mimic PTSD, such as hyperthyroidism which can create an anxiety state.
