How soon can Xanax be detected in urine?

Theraven13,

It should test positive; so you shouldn't have anything to worry about; benzodiazepines such as xanax are detectable in the urine for a few days from single use and for a few weeks in daily use.

At least they used an expanded panel test, necessary for detecting BZ.

Low dosage and dilution could cause a problem. Metabolites are measured in proportion to volume and concentration of urine. BZ uses a cutoff of 200 ng at the screening level. The drug must be present and in sufficient quantity to rise above the cutoff.

Ingestion of water in close proximity to drug testing is contraindicated. Dilute urine results in less drug per unit of urine. You should have been asked to wait.

Was that noted on your form?

They didn't note anything. I even told them that I urinated 3 times before I was called in because it didn't know anything about having to take a urine test. They never asked me my current meds or otcs or even let me read or explain the permission slip that I signed. Everything happened so fast and I didn't want to offend my doctor of 14 years but everything was kind of done unprofessional and half-assed. If it comes back negative should I tell my doctor all this and demand another test before I lose him as a doctor and lose my required meds?

Where was the sample provided, a collection center or the doctor's office?

At my doctor's office in one of those integrated cups.

Please explain "integrated cup". Do you mean an instant test? Or was the sample sent out to a lab?

I never asked, but it looks like one of those that you get your results in 5 minutes and if you want to send positive results to a lab for confirmation you can but it's optional.

The cup was not your average cheap urine specimen cup. It was flat in the back and had a cylinder in the bottom and decal decoration all over it. The kind some doctor's offices use to lay down and xerox the results. I guess they wouldn't send it to a lab unless I tested positive for illegal drugs which I don't do illegal drugs. I just want my doctor to know I take my xanax , I am allowed to take up to 3 mg a day everyday, but it says as needed so I average 0.5- 1mg a day unless I'm under a lot of stress like now. Over the weekend I took only 1 every night and 0.5 the morning of the test. But I've been taking a minimum of 0.5- 1.0 xananx every night for a year.

It could be either one. Some collection cups check nothing but temperature and creatinine and ensure the sample it is not adulterated.

However, if it was an instant test, then they knew the results while you were there.

Sounds like you will just have to wait and hope for the best. It is possible that it will detect the BZ. Just poor collection practice.
