Diagnostics and disease monitoring is the cornerstone of modern medicine. All inpatient and outpatient medical and surgical care depends on access to advanced diagnostics as well as having the ability to monitor disease over time. Many aspects of pediatric diagnostic medicine are affected by the unique aspects of caring for children.

Our specialists perform vital diagnostic, therapeutic and blood collection services for all patients at our hospital, as well as at our outpatient centers and mobile health units in the Washington, D.C., metropolitan area. Using state-of-the-art technologies and techniques, our team completes more than 1,000,000 tests annually to assist physicians in confirming a diagnosis or in monitoring the effectiveness of a child’s treatment.
