Laboratory Studies
Basic laboratory studies are prudent to detect contraindications to medication treatment, as well as to screen for comorbid conditions such as anemia, low ferritin levels (especially in the presence of a sleep disorder), and hypothyroidism. Such studies might include a serum CBC count with differential, an electrolyte evaluation, liver function tests, and thyroid function tests.
Imaging Studies
Neither single-photon emission computed tomography (SPECT) nor functional MRI (fMRI) is clinically helpful in the diagnosis or treatment response in individuals with social phobia. However, these techniques are useful for excluding structural brain disease (tumor or infection). These techniques are also being used investigationally in research protocols; it has been shown that social anxiety is a different disorder from generalized anxiety disorder in terms of symptomology and brain structure.[30]
Other Tests
In general, social phobia is not associated with mitral valve prolapse, so echocardiography is unnecessary unless clinically indicated because of other symptoms or history.[21]
