They were identified in the 1800s (John Tyndall developed a process for destroying them with intermittent heat procedure), although the stain procedures to identify them did not develop until the early twentieth century. Of the three processes available to monitor sterilization, only biological monitoring directly monitors the lethality of a given sterilization process, according to the CDC.¹ If a sterilizer is used frequently (e.g., several loads per day), daily use of biological indicators allows earlier discovery of equipment malfunctions or procedural errors-minimizing the extent of patient surveillance and product recall needed in the event of a positive biological indicator.Īccording to the CDC, as well as the American National Standards Institute (ANSI) and Association for the Advancement of Medical Instrumentation (AAMI), steam sterilizers should be monitored at least weekly, preferably every day the sterilizer is run.įor a handy reference guide, download our in-office biological indicator for monitoring steam processes poster.\)Įndospore production is a very important characteristic of some bacteria, allowing them to resist adverse environmental conditions such as desiccation, chemical exposure, extreme heat, etc. Commercially available BIs are non-pathogenic (harmless) and are specific for the type of sterilization process being monitored. Biological Indicators (BIs) are considered the highest level of sterility assurance because they actually test the sterilizer's ability to kill specific strains of highly resistant organisms. (6) Use of a biological monitoring system (spore tests). That still doesn't mean your autoclave is properly sterilizing your instruments!īiological monitoring manages sterilization with the use of bacterial spores. The date the sterilization was performed must be applied to the sterilization pouch while being stored. It appears you've achieved the necessary physical and chemical conditions for sterilization. To view your spore test results please login with your customer number & phone number. Your sterilizer might be free of obvious mechanical malfunction, and you might also be certain the sterilizing agent is penetrating the package and reaching the instruments inside. Infection Control Educational Resourcesīiological Techniques for Monitoring Your Autoclave and Ensuring Optimal Sterilization.The results of a 'negative' test indicate sterilization. The desired outcome of biological testing is the killing of the spore challenge. At least weekly spore testing is recommended. Testing kits are for use in steam, chemical vapor, dry heat and EO gas sterilization processes. Also, spore testing is an essential part of the evaluation of any repaired sterilizer prior to placing it back into use. Supply Chain Best Practices During The Pandemic Sterilizer Spore Test Kits for Sterilizers, Package of 52.InControl - Infection Prevention Products.InControl - Infection Prevention Information Biological indicators, or spore tests, are the most accepted means of monitoring sterilization because they assess the sterilization process directly by killing known highly resistant microorganisms (e.g., Geobacillus or Bacillus species).It is the customers responsibility to remove access to users that may no longer be with the company. Because Spores Dont Lie Spore tests help assess the sterilization and compliance of ridding highly resistant microorganisms.
