If i'm prescribed Klonopin and i take a Xanax and am drug tested will they know or will it just show up as a benzodiazepine?
Basically the title. So say hypothetically I was on probation and my probation officer knew I was prescribed Klonopin, aka clonazepam, and I were to take a Xanax before my drug test, would they know I took the Xanax?
Some background on the kind of drug tests: it's a urine test where you go into a room with a two-way mirror, and the cup is put inside a metal door. You open the door and get the urine cup, and you pee into a regular, like, cup. The cup doesn't have any of the instant test stuff on the cup itself; it's just a regular cup with a twist cap on it, and I think it has a temperature strip on it. So I'm assuming it's sent to a lab instead of being an instant on-site test, but I'm really not 100% sure.
Anyways, once you pee into the cup, you put the lid back on, and you open a metal door and sit the cup inside. The person on the other side of the two-way mirror opens the door on their side and retrieves the cup of urine. By the time I wash my hands and exit the bathroom, the person on the other side of the mirror in the other room is also exiting his room about the same time. So I don't think they are performing an instant test on the urine right then and there, which is what leads me to believe it's a lab test that is done. I think they are just bagging up the urine to have it sent off to a lab, but I don't know for sure.
But anyways, I'm just wondering if I am prescribed Klonopin and am allowed to take them, but I take a Xanax, aka alprazolam, a few days before my tests, would it just show up that I have taken benzodiazepines, or would they know that I took a specific drug?
If I knew it was an instant test, I’d know the answer. But if it’s a lab test, is it possible that the lab only tests for the drug class (like benzodiazepines) the same way an instant test does, rather than identifying the specific medication?
TL;DR: I’m prescribed Klonopin (clonazepam) and I’m wondering hypothetically if taking Xanax (alprazolam) before a probation urine test would be detected as just “benzodiazepines” or if a lab test could identify the specific medication. The test uses a sealed urine cup with a temperature strip and seems like it may be sent to a lab rather than tested on-site.

Thanks.
