Minnesota Monitoring provides random drug and alcohol services:
Minnesota Monitoring offers a Random Drug and Alcohol Testing Program called Sentry. When a client is enrolled on the Sentry program, the client will receive a unique pin number. The client is required to call into the system daily and enter their pin number. Once the system identifies them, it will notify them if they are to report for testing or not. The system tracks the time they call in as well as the telephone number they call from. Other benefits:
Web check in options available for clients without telephones
Customized programming allows for different monitoring needs.
