Biologic spore testing7/2/2023 Retest at that time with biological indicators in three consecutive sterilizer cycles. Repeat the biological indicator using a different manufacturer’s indicator.Ĭlose sterilizer down until the manufacturer can assure that it is operating properly.Discuss the abnormalities with the sterilizer manufacturer.Have hospital maintenance inspect the steam supply lines.Request an inspection of the equipment by sterilizer maintenance personnel.If one or both biological indicators are positive, do one or more of the following until problem is resolved.If all three repeat biological indicators from three consecutive sterilizer cycles (step 2 above) are negative, put the sterilizer back in service. If steps 1 through 5 resolve the problem Spore tests remain the gold standard for monitoring the sterilization process because they assess it directly by killing highly resistant bacterial spores rather than merely testing the physical and chemical conditions necessary for sterilization. Duo Spore Biological Indicator Test - 12 Test Envelopes No Processing 4593-424 1D295609866A3EDE294A9A38B9D93D91.If not, repeat using appropriate settings. The spore-forming microorganisms used in biological indicators are well characterized. Check to ensure the correct biological indicator was used and appropriately interpreted. Medical device testing, Sterility testing / By Ethide Laboratories.Any abnormalities should be reported to the person who performs sterilizer maintenance (e.g., medical engineering, sterilizer manufacturer). Check with hospital maintenance for irregularities (e.g., electrical) or changes in the hospital steam supply (i.e., from standard ≥97% steam, If not, repeat using appropriate settings and recall and reprocess all inadequately processed items. Check to ensure the sterilizer was used correctly (e.g., verify correct time and temperature setting).The items from the suspect load(s) should be recalled and reprocessed. If additional spore tests remain positive, the items should be considered nonsterile, and supplies processed since the last acceptable (negative) biological indicator should be recalled. As soon as possible, repeat biological indicator test in three consecutive sterilizer cycles. Objects, other than implantable objects, do not need to be recalled because of a single positive spore test unless the sterilizer or the sterilization procedure is defective.Notify area supervisor and infection control department.
