In protocol review, the 3Rs stand for which of the following?

• A. Replacement, Reduction, Refinement.
• B. Regulation, Review, Reporting.
• C. Randomization, Replication, Rigor.
• D. Rescue, Rehabilitation, Rehoming.

Answer: (A)

In protocol review, the 3Rs guide how research is planned to minimize animal use and suffering. Replacement means using non-animal methods whenever possible, such as cell cultures, computer models, or cadaver studies, before any animal work is considered. Reduction focuses on designing experiments to obtain the same level of information with fewer animals, through proper statistics, power analysis, data sharing, and avoiding unnecessary duplication. Refinement involves modifying procedures to lessen pain, distress, or lasting impacts on animals, including better anesthesia and analgesia, improved housing and handling, humane endpoints, and less invasive techniques. These three principles form the ethical framework researchers and committees apply to justify and optimize studies involving animals. The other options refer to different ideas: Regulation, Review, Reporting concerns oversight processes; Randomization, Replication, Rigor relate to study design and robustness; Rescue, Rehabilitation, Rehoming are welfare actions but not the triad used in protocol review.
