Which laboratory type is owned and operated by an external entity and offers testing across several specialties?

• A. In-house Laboratory
• B. Reference Laboratory
• C. Public Health Laboratory
• D. Mobile Laboratory

Answer: (B)

Understanding how labs are owned and what services they offer helps explain why a reference laboratory is the best fit. A reference laboratory is owned and operated by an external entity, not by the hospital or clinic where the patient samples originate, and it provides testing across multiple medical specialties. This broad menu and external ownership allow it to serve many clients (hospitals, clinics, physician offices) and perform advanced or specialized tests that a single facility might not run in-house. In-house laboratories are owned by the health system and focus on tests needed for their own patients with close integration to care. Public health laboratories are government-run and concentrate on population health, surveillance, and regulatory testing rather than broad clinical testing for individual patients. Mobile laboratories travel to sites for on-site testing and may not offer the same breadth of specialty testing as a reference lab.
