Just an FYI here......I'm on probation as well. When my test are done at my PO's, it is at her discretion if she wants to just use a stick or send it to a lab. If I happen to be testing after a bi-week of not testing then she will send it to the lab. After the week of a lab test she will generally test a couple of times with the stick. It's not random that I get tested....it's just random of which way she will have it tested.
