Patients and visitors are required by law to wear masks in all healthcare facilities, regardless of vaccination status.

Our medical laboratory services provide continuity of care between emergency, inpatient and outpatient testing events. We perform outpatient diagnostic testing for infants, children and adults. Our services are available by scheduling an appointment online or on a walk-in basis at numerous patient service centers throughout the region.


Specific tests, including timed studies, should be scheduled by calling Client Services at 540.741.3415 for the patient’s convenience and to receive appropriate instructions.
