I have been producing false negatives on my screens for probation using the dilution/asprin method. Always with at least 3 days clean before each test. One day I had smoked the night before and ended up having to do a screen. I did the dilution thing and also dipped my finger in bleach and then let the urine hit my finger on the way into the cup. It worked for me twice even though they test the PH with a seperate "dipstick".

I tried it again on a thursday and it did not work. I'm not sure why. So, since it was positive it was supposed to be sent for gc/ms confirmation that night. They told me they would have the results monday at the earliest. When I called Monday they could not find the file. They called me back about an hour later and said they made a mistake and had not sent it to the lab yet so they needed a couple more days before I could get the results. I dont know if the sample was kept at room temp. or in a fridge.

So my question is: A) Will the fact that the urine sat for at least 4 days with bleach in it effect the confirmation? B) How long can urine sit and still give an accurate reading for THC? and C) I signed a "chain of custody" aggreement in order for them to send it for confirmation. Do I have a legal argument that the "chain of custody" was or may have been broken when they lost my file and could not find my sample? Or that the urine was to old to produce accurate results?

Any help/advice is greatly appreciated. I am nervous as hell!!!
