@whitechocolate,
Just to put this in perspective: I don't know your situation, the job you are going for, where you are located and the respective privacy laws in that jurisdiction, so I just want to give you an outside scenario.
Valium has a half-life of roughly 20-100 hours or longer depending on the dose and frequency of administration. In a standard 10-panel screen for an employment screening, for example, it will show up as a b3nz0di@zepine. You must, therefore, present a valid, current prescription for a b3nz0di@zepine and you s/b okay. It is possible, for example, to use a current prescription for L0r@zep@m to explain a positive b3nz0 screening result for Valium. Screens can vary by industry to industry and screening services report differently. A service we use would provide a single report in such a case to my HR department that says something like:
Name: John Doe
DOB ...
etc.etc. etc.
-------------
Nationwide criminal search: Clear
Yukon County criminal search: Clear
FDA Debarments: Clear
FACSIS: Clear
etc.
etc.
U/A Screening: Clear
and that's it, because you've provided an Rx that explains your positive screen in that category.
However, an employer can always order other tests, and for certain types of jobs, if they are suspicious they can drill down into each category. Each service reports detailed screening differently. My service requires written authorization to do any background checking or screening and to provide anything more than the basic report. Others may not need additional authorization because they obtained it with your first signature in which case they could provide a more detailed report, because you will have signed off, that says something like:
0p!@tes: Negative
@mph3t@mines: Negative
etc.
etc.
B3nz0d!@z3pines: Positive with Prescription
It varies, so read what you sign.
Your prospective employer can then approach you and say, "Hi, WhiteChocolate, we'd like to run one or two more checks if you want this job. Please report to 1111 South Yukon St, North Pole 11111, and sign off..." Or, they may gain your authorization to dig further on your initial authorization form. This is not typical, however, but if you are looking to be an air traffic controller, for example, it may be standard.
In a worst case scenario, a suspicious employer could dig in and in such a case a GC/MS confirmation test will show a metabolite of nord!@z3pam in your U/A, which is specific to V@l!um.
Now, keep in mind that most employers that have lots of employees have a budget and they want to keep their costs down. A 10-panel screen costs our company $52. A full GC/MS test (necessary to pull that specific metabolite) costs us anywhere from US$450-950.
So... read what you sign, think about the job you are going for and remember that V's have a looooong detection time via U/A.
Hope this helps.
