It is unlawful for any person to own, operate, maintain, direct, or engage in the business of operating a clinical laboratory, as defined in this chapter, unless he or she possesses a valid clinical laboratory license issued by the department. In the event a health facility does not perform clinical laboratory services, but provides laboratory services to its patients under an agreement with another person or entity that holds and is operating under a valid clinical laboratory license, the health facility shall not be required to obtain a clinical laboratory license.
