Which term describes the practices and procedures to prevent contamination from pathogens?

• A. Aseptic technique
• B. Sterilization
• C. Disinfection
• D. Sanitation

Answer: (A)

Aseptic technique is the set of practices and procedures used to prevent contamination from pathogens. It includes hand hygiene, donning sterile gloves, using sterile instruments, creating and maintaining a sterile field, and careful handling to avoid introducing microbes into a patient or specimen. This focus on preventing contamination during the procedure distinguishes it from methods that kill or remove microbes after they’re present. Sterilization, for example, is about destroying all forms of microbial life, including spores, often through heat, chemicals, or radiation. Disinfection targets reducing or eliminating pathogens on inanimate surfaces but may not kill all microorganisms or spores. Sanitation lowers the overall microbial load to a safe level, but it’s not specifically about preventing contamination during the procedure itself.
