2017 Biological Indicator Service for Steriliser Validation for all office based practice


Annual validation of steriliser function is part of the total annual validation process. Staff are also expected to address instrument cleaning, policy, staff education, maintenance and monitoring as part of annual validation.


7 Biological Indicators (BIs) and / or incubation and a report are provided. Posted with BIs are instructions, a template and an express envelope for return post. Phone support is available at no extra cost. Total cost is $110 or $66 for a single component eg. BI tests only.


For most bench top sterilisers, 7 Biological Indicators are sufficient. These are placed in difficult to sterilise parts of the chamber. They contain a difficult to kill bacteria as a challenge. The sterilised tests are then returned for incubation.


The role of the staff, after the service technician has completed preliminary testing using the challenge load prepared by staff, is to place BIs in various locations of this load and run three identical, consecutive loads, each with two BIs. The seventh test is a control. All are posted in the padded express envelope provided for 48 hours incubation.
