**  A POSITIVE test result means that not all the bacterial spores were killed and the items processed in that load may not be sterile.  Repeat the test following the guidelines above.

** In the event of a second POSITIVE result, after all items above were observed, discontinue using your sterilizer until it has been repaired or inspected, or until the exact reason for the POSITIVE test has been found.  Use another sterilizer.  Instruments may have to be re-sterilized.
