Utility of Nonspecific Laboratory Testing for Psychiatric Patients Undergoing Medical Screening in a Military Emergency Department.

Introduction: Psychiatric complaints account for a sizable and increasing portion of emergency department (ED) visits.

This can prompt early and indiscriminate laboratory testing to expedite early requests for admission consideration.
