As reviewed in a past article, the field of Psychiatry is unique among medical specialties. At present, medical technology has yet to provide adequate imaging or laboratory testing that would allow for more objective assessment of a patient’s symptoms and concerns. A person with chest pain, fatigue and a racing heartbeat can rest assured that a carefully designed testing protocol will clarify the nature of the problem. Cardiac enzymes, electrocardiogram, chest x-ray and even cardiac catheterization will provide objective evidence to either rule-in or rule-out a cardiac event. Or the severe sore throat that makes swallowing difficult can be objectively clarified by obtaining a throat culture and consequently help the physician chose an antibiotic if indicated.
