On probation for theft, is it likely that they will test me for methadone.?

I live in Indianapolis Indiana and go to the Marion County building. I have not ever been in trouble for drugs. I realize methadone is part of an extended test and will not cause a false positive for opiates. I really just want to know if they are likely to test me for methadone. This will also be my first test because my probation started 3 weeks ago. Thanks very much and hope to have any input.
