What licensure/certifications must the lab director have?

• A. DO
• B. RN
• C. MD
• D. PhD

Answer: (C)

Licensure for the lab director centers on medical oversight of patient-oriented testing. The person in this role is responsible for medical decision-making related to test results, ensuring accuracy, quality, and interpretation within the clinical context. Because this involves practicing medicine within the lab setting, a physician licensed to practice medicine is required. Among the options, only an MD carries an active medical license that authorizes this kind of medical direction under typical regulatory standards. A registered nurse is licensed for nursing care but not for medical oversight of laboratory testing; a PhD is a researcher or scientist but generally lacks medical licensure; a Doctor of Osteopathy is also a physician, but the standard answer reflects the MD licensure as the typical expectation.
