I still need more information on why I failed a drug test for
methamphetamines I am not using this of any kind legal or illegal. 
The MRO states their is no way there had been a mistake of anykind of
misinterpeting the meth found in my urine sample or any meds has been
used to cause a positive result. "urine test don't lye".
I have gone to my Doctors and I get the feeling that they will not
even talk about the possibilty of UA can give a false Positive.  I
getting very fustrated and still stand by my original response not
guilty.  I asked for a hair sample drug testing and the MRO states
thats not a choice.  The only choice is to have my original urine
(that is frozen) to be retested at a diffrent lab of there choice.  It will cost me
200.00 and how do I know that the sealed vial has not been tampered
with?  My employer I am sure is catching a huge heat from above to
find a person guilty with tampering with a stimulant.  I understand
that the others that came back positive have a prescription and that
eliminates .  I need a
advocate to prove my innocence.  Is there 100% proof that either cold
medicine, kidney and uti infections or Provigil would cause this? 
Some one help me soon so I don't loose my nursing license. One more
thing is how long can the original collected urine that is frozen stay
good for.  I would thing it would make my case worse if I have not
seenthe vial to see if unsealed or not. Doen anyone want to challenge
this questions with facts and not something someone else has already
sent me?

I, too, have tried to help:

A problem that I don't think we can solve, though, is this: providing
evidence that something *can possibly* cause a false positive does not
prove that it *did* in a certain case.

Dale, if I were in your position I would seek legal counsel.

Dale,

I agree with my collegue, it's time to contact an attorney.  And
document all your efforts, and all events up to this point.

Is the MRO employed by your company or an independent lab?  If it is
an independent lab they will not likely have a problem with explaining
exactly how their testing is done.

Ask if they used both "EMIT" testing and "GC/MS."  It is common to use
both tests to confirm, as described by this service:

If it is an independent lab I would think they already did it all
correctly, but if it was done "in house" who knows what they do.
