What are the parameters of this UA.

0 you pass... if you are being tested for anything other than an employment screening you are supposed to be abstaining. If you are unable, you should look up the services of AA or some other similar entity who can help you. I've been subject to random testing as part of employment conditions for over 35 years....never had to worry.

The parameters are set by whomever is requiring the test. Who is requiring yours?
