Laboratory Services

The Commission on Laboratory Accreditation of the College of American Pathologists (CAP) accredits the Laboratory at Magruder Hospital.

Stringent inspection of the laboratory's records and quality control procedures, along with examination of the entire staff's qualifications, the laboratory's equipment, facilities, safety program and record, as well as the overall management of the laboratory, ensures the highest standard of care for the laboratory's patients.

The Laboratory at Magruder Hospital has earned AABB Accreditation. AABB is formerly known as the American Association of Blood Banks.
