Aseptic technique is a process designed to protect clients during invasive clinical procedures using infection prevention and control measures to minimise the presence of pathogenic microorganisms. This is achieved by identifying and protecting key sites and key parts, consistently applying the following principles:

• good hand hygiene
• correct and appropriate use of personal protective equipment (PPE)
• using sterile equipment, or appropriately cleaning and allowing to dry, key parts to a standard that ensures they are aseptic before use
• use of a non-touch technique throughout.
