Which lab type is owned and operated by an external entity offering testing in multiple specialties?

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

Answer: (C)

A reference laboratory is an external entity that is owned and operated by another organization and provides testing across a wide range of specialties to multiple healthcare providers. Because it sits outside any single hospital or clinic, it serves many clients and offers a broad menu of tests, often including complex or specialized assays that smaller facilities cannot perform in-house. This combination of external ownership and multi-specialty testing is what distinguishes it from the other options: an in-house laboratory is owned by the organization it serves and has a more limited test menu, public health laboratories are government-run and focus on population health and surveillance, and mobile laboratories are mobile units that travel to sites and may not offer the full breadth of testing across specialties.
