The Division of Diagnostic Medicine provides comprehensive evaluation, diagnosis and treatment services to infants, children and adolescents with complex or mysterious problems.  The Diagnostic Center is an innovative outpatient resource that assists general pediatricians, family practitioners and St. Louis Children's Hospital staff in the prompt assessment of patients with a broad variety of complaints, particularly those that fit poorly into a single subspecialty area.  The center serves patients who require diagnostic work requiring a medical center setting and those who pose a "diagnostic dilemma."
