Unsatisfactory Result?

Several factors may cause a biological indicator test failure, and a single failure is not necessarily an indicator of faulty equipment. It is important to retest your sterilizer as soon as possible.

Your sterilizer monitoring report will show you a list of recommendations in case of a failure, however you can find more detailed help below.

Failure-Step-1

Check Test Conditions

Check to ensure the sterilizer was set using the proper test conditions (Temperature, Time, Pressure). Most steam sterilizers operate between 250 – 270 degrees F. Temperatures outside of this range will likely fail to kill all organisms. 

Failure-Step-2

Verify Load Capacity

Verify that the sterilizer was not overloaded when the strip was run. It is important not to exceed the load capacity as it is listed. The steam/heat/vapor must be able to flow around each item being sterilized.

Failure-Step-3

Inspect Door Gasket

Check the door gasket on the sterilizer. A cracked or improper fitting gasket will impair the ability of the sterilizer to reach the proper pressure. Loss of pressure can result in inadequate sterilization.
