Which of the following defines a conflict of interest?

• A. An official policy that prevents any personal influence.
• B. A personal interest or relationship, as defined by law or regulation, that conflicts with the faithful performance of your official duty.
• C. A fixed work schedule that avoids conflicts with lab tasks.
• D. A definition of data integrity.

Answer: (B)

A conflict of interest arises when a personal interest or relationship, defined by law or regulation, could interfere with faithfully performing your official duties. In a lab supervision context, this means any situation where something outside your official role—like a financial stake in a supplier, a family relationship with someone you supervise, or gifts that could sway your judgment—might influence your decisions or actions. The key idea is that personal incentives should not compromise objective, impartial judgments required by your role.

The other descriptions aren’t about conflicts themselves: one is a policy designed to prevent personal influence, not the definition of the issue; another is simply a scheduling detail unrelated to impartial decision-making; and the last is a term focused on the accuracy and reliability of data, not on competing interests. Recognizing and disclosing these interests helps maintain integrity and trust in the lab.
