While in office systems offer faster turnaround time of results, mail in systems are considered easier to use. Both systems should provide the same level of sterility assurance if performed correctly. Which is better, in office or mail in spore test systems?Ī. Canadian Standards (CSA) say to test sterilizers the first load of the day and every load that contains an implant. EO gas and hydrogen peroxide processes, should be spore tested each load. AAMI and AORN standards recommend steam sterilizers be spore tested at least weekly, preferably daily and every load that contains an implant. According to the CDC, sterilizers should be tested at least weekly and every load that contains an implant. How often should sterilizers be spore tested?Ī. Crosstex/SPSmedical is used and recommended by leading sterilizer and instrument manufacturers. Crosstex/SPSmedical provides three different mail-in spore testing products to choose from, including the PassPortPlus, which provides immediate information about the Steam sterilization cycle, allowing failures to be detected before the spore test results have been communicated by the test laboratory. Upon request, Crosstex/SPSmedical provides a complimentary educational program, “Cleaning, Packaging and Sterilization of Instruments” which is based on sterilization best practices and is approved by IAHCSMM and CBSPD for continuing education credit. Crosstex/SPSmedical is a corporate member of both AAMI and CSA, where we contribute to writing sterilization standards. How is Crosstex/SPSmedical different than other test laboratories?Ī.

Per Section 6.3.2 of ISO 11138-2, if the end-user population verification performed during the manufacturer’s stated shelf-life results in a population below 1×10 6 but still falls between 50% to 300% criteria, the verification is acceptable.Frequently Asked Questions Q. Verification of the population is achieved if the test result is between 50% and 300% of the nominal certificate population. Results are then compared to the manufacturer’s certificate nominal population.

Manufacturer and biological indicator product methods may vary in extraction techniques, as well as heat-shocking and incubation temperatures of different test organisms, and appropriateness should be verified by end-user performing the test.įollowing the incubation period, the colony forming units (CFUs) are enumerated and the results recorded.

ISO 11138-1 defines the minimum sample number of four biological indicators for population verification.īiological indicators are assayed following manufacturer’s instruction, usually involving extraction, and sometimes requiring maceration of a paper strip, heat-shocking, serial dilution, pour-plating, incubation, and enumeration. To verify the spore population of the test organism, samples of biological indicators are selected from each distinct manufacturer batch per delivery received.

How to the Population Verification is Performed Manufacturers are required by ISO 11138-1 to provide the name of the test organism instructions for use, storage, testing, and disposal and the nominal population and resistance information with each biological indicator batch. Moist heat and vaporized hydrogen peroxide (VHP) modalities typically use a thermophilic endospore-forming bacteria, Geobacillus stearothermophilus.

The transit and storage conditions have not affected the spore population.

The spore population is as stated by the manufacturer on the certificate of analysis (COA).

This spore population should be verified prior to use for routine sterilization purposes, to ensure that: In ethylene oxide and dry heat sterilization, the test organism used is typically the endospore-forming bacteria, Bacillus atrophaeus, (ISO11138-2 Sterilization of health care products – Biological indicators – Part 2: Biological indicators for ethylene oxide sterilization processes and ISO11138-4 Biological indicators – Part 4: Biological indicators for dry heat sterilization processes) with each unit having a minimum population of 1 x 10 6. The population of the test organisms upon receipt at the test facility should be verified per ISO 11138-1 Sterilization of health care products – Biological indicators – Part 1: General requirements. In a sterilization process where biological indicator (BI) sterility results are used as part of product release criteria, the BIs shall be procured from an approved supplier with a minimum population of test organisms defined.
