test pure?

I fell at work and was drug tested the following day i am a smoker...but i did use test pure and yes i did do exactly as the directions told me....and i have used it for years without any problems...this time I came up positive for THC. So it was sent out to the lab for further testing...I was told to list all meds currently taking which included ibuprofen,phenergan and vicoden. i know all of these can cause a false negative for THC. So what kind of tests will the lab do? will i still test positive for THC? help please i'm so worried :(

There are no false positives anymore, period.

Why would they make you list the meds you are on? That practice went out long ago as that is now the job of the MRO to discuss any meds you are on if you come up positive for a prescription control. This is to add to your privacy because there is no reason for the collector to know this.
