She did tell me that I needed to get down to the 50 ng to be clean, so I don't know what they are doing because an assay screen wouldn't show the level right?
Exactly. Assays have no ability to give a quantitative analysis like Ive already stated. A GC/MS has to be performed in order to obtain quantitative values. And the GC/MS does not have a 50 ng cutoff threshold, so theres yet another example of the P/O not knowing what the hell s/he is talking about.

I am drinking Smart Water and Powerade Zero, will that help or is fluid fluid when it comes to these things?

Fluids like powerade or gatorade are more helpful than water because they help keep the S/G (specific gravity) within satisfactory ranges. S/G is tested along with creatinine in order to determine an overly-diluted sample. Drinking a bunch of water causes the S/G and creatinine levels to take a nosedive and thus sending up the "diluted" flags at the lab.
Burnt Toast Reviewed by Burnt Toast on . Random Drug Testing I was wondering if anyone has any knowledge on my problem. I am on probation and have random drug tests. They waited 45 days to do a baseline test on me and ever since this PO has been on my ass accusing of being a liar and she says I have to be still using. My 1st test I was at 198 and was a chronic smoker, all day every day, so I imagine I was probably way higher back then. A this time she told me that I should have been clean in 30 days so she was going to monitor me closer. So she tests me Rating: 5
