Sterilization and disinfection are often used interchangeably in conversation; in a regulated facility they are different processes with different evidence. Sterilization destroys all forms of microbial life, including bacterial spores — typically by steam under pressure — and is proven by physical, chemical, and biological indicators on every cycle. Disinfection reduces the microbial load by degrees: high-level disinfection inactivates everything except large numbers of spores, while low-level disinfection handles everyday surface organisms.
Which process a device requires isn't a judgment call — it follows from the device's Spaulding classification. The compliance failure assessors see most isn't choosing the wrong chemical; it's being unable to prove the right process ran: no cycle record, no indicator log, no test strips for the disinfectant's concentration.
Why it matters
The distinction drives purchasing, workflow, and record-keeping. A facility that can articulate it — and show the logs — walks through the reprocessing portion of any inspection.
