monitoring systems are designed for specific
sterilization methods, you must be sure to use a system
compatible with the sterilization method used. The
following test procedures should be used to ensure
effectiveness of the sterilization process:
The use of a test pack is most practical while
processing an instrument pack.
Biological spore strips or ampules should be
placed between several layers of folded
wrapping material, and then the test pack is
double-wrapped in the normal manner.
Always follow the biological monitor
manufacturers directions for the placement of
the test pack within the sterilizer.
As a general rule, the biological spore strips or
ampules should be placed within an area of the
sterilizer that is least accessible to the sterilizing
agent that is being used.
If using steam under pressure sterilizers, place
the test pack in the lower front of the sterilization
If using tabletop units, place the test pack in the
center of the load.
For each test, use an unprocessed monitor for a
