How do you use biological indicator strips?

How do you use biological indicator strips?

After exposure to sterilant, incubate strips at 55-60°C. Bacillus atrophaeus* – For use in Ethylene Oxide (600 mg/L) and Dry Heat Sterilization (D-value calculated at 160°C). After exposure to sterilant, incubate strips at 30-35°C.

How do you perform a biological indicator test?

Biological Indicator Testing Procedure The carrier material is enclosed within a glassine envelope or a vial. The BI is exposed to the sterilization process and then incubated under defined growth conditions to determine whether any spores survived the process. If no spores survive, none grow and the test is a pass.

How do you monitor sterilization process?

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).

How do you use spore strips?

Traditional Paper Biological Indicator (Spore Strips) To use, simply place the envelope inside a product or product package. This “inoculated package” is placed in a sterilizer and processed. Upon removal from the sterilizer, the inoculated package is sent to the microbiology laboratory for transfer of the Strip.

How often should you use a biological indicator to monitor the autoclave?

How often should biological monitoring (spore testing) be done? A spore test should be used on each sterilizer at least weekly. Users should follow the manufacturer’s directions for how to place the biological indicator in the sterilizer. A spore test should also be used for every load with an implantable device.

How do you confirm sterilization?
