Overview

Need a blood draw or other physician-ordered lab test? Inova's expert lab facilities can perform almost all labs tests onsite. Any tests not conducted onsite will be sent to Inova's central lab for processing.

All lab tests require a signed physician order. Please note: in the event of inclement weather, hours are subject to change.
