Two phlebotomists discuss a patient's positive test result by name in a crowded elevator. Which principle is violated?

Identifiable health information may be disclosed only to those with a legitimate need to know, and a public elevator conversation exposes it to people with no treatment relationship. Chain of custody concerns forensic specimen tracking, quality control concerns test accuracy, and informed consent concerns permission for a procedure. None of those cover casual disclosure of results.
