Medically Aseptic Objects: Definition and Microbial Status

An object that is medically aseptic (sterile) is free of all viable microorganisms—bacteria, viruses, fungi, and spores. By definition, no microorganisms are present on a truly aseptic item.

Asepsis is achieved through validated sterilization processes (steam autoclave, ethylene oxide, hydrogen peroxide plasma, radiation) and maintained by sterile packaging and handling.
