Biologic Sterilizer Monitoring
This service is provided by our Division of Oral and Maxillofacial Pathology. It involves the monitoring of heat sterilizers using a biologic indicator to test the effectiveness of the sterilizer in killing microbial life, and is the only true test of effective sterilization.
Subscribers to the service receive a year's supply of test forms and biologic indicator test strips and control strips. The biologic indicators are filter paper strips impregnated with spores of Geobacillus stearothermophilus and Bacillus atrophaeus enclosed in a glassine envelope.
- The biological indicator is placed in a typical sterilization load.
- At the end of the sterilization cycle, the biologic indicator test along with an unprocessed control is mailed to the monitoring service for culturing.
- Positive results, indicative of ineffective sterilization, are called to the office immediately and are verified by a gram stain.

After 19 years of operation, we've performed more than 30,000 routine tests for subscribers. Sterilizers tested include autoclaves, chemiclaves and dry heat sterilizers.
Failed tests are repeated, and if the retest is again positive, equipment malfunction is indicated and servicing followed by another test is recommended. If the first retest is negative, a load processing problem is indicated.
Routine biologic monitoring by subscribers has resulted in early detection of sterilization failures, allowing corrective measures to be taken.
