High Anxiety, seeking input

Hi everyone,

I am in place to start an internship with a Fortune 500 company pending I pass a drug screen. I took it last week with LabCorp/ChoicePoint. I smoked for the first time in 5 and half months, 25 days prior to the test. I also stupidly took a tylenol 3 (with codeine in it) and 20 mg of oxycodone about 4 and half days prior to the test. In my defense, I didn't know I would be getting drug tested when I consumed these substances, and would never have done so otherwise.

Anyways the day of the test I took 4 aspirin 8 hours before the test, a couple of B-complex vitamins an hour before it, and drank probably 125 ounces of water and 54 ounces of Gatorade in the hours leading up to it. However I was on adderall leading up to the test because I am prescribed it.

When I took the test, my pee was pretty watery, with a yellow tinge to it. They sent off my sample immediately and said that I'd hear from a doctor if I tested positive for any substances (adderall-amphetamines). It's been 3 days since the test, and today my company got impatient with LabCorp and dug up my results. They said I tested positive for amphetamines, and that the lab was running the sample through a couple more "confirmation" tests to "see if there was anything else".


So my question is: Do you think that these "confirmation tests" are specimen validity tests (I'm almost positive my sample is diluted)? Or do you think they are sticking it into a more sensitive GC/MS test? And if they are using a GC/MS confirmation test, can they only test for the amphetamines, or can they see if I test positive for other drugs that I tested negative for on the EMIT?

I called LabCorp myself to see if I could provide them my prescription information so they didn't run me through the GC/MS gauntlet and find something they didn't before. But they said the test results hadn't come in yet and a doctor would call me first thing if I was testing positive for anything. So I'm guessing my company dug really deep.

Sorry this is kind of a long and complex situation and it's eating me alive, if anyone can weigh in and give me an honest assessment of what they think is going on I'd really appreciate it. Thanks

By the way, I'm 5'9, 150-155 pounds. lean and skinny build. I took 2 CVS drug tests 2 days prior to the screening and passed them both for THC, opiates and oxycodone (failed amphetamines which is alright). The day after the test I went home and took one of the drug tests my parents use on me (which for some reason seem to be more sensitive than the CVS ones), and I passed for THC and opiates, but my THC line was pretty faint. I didn't dilute my sample on the home tests like I did on the actual screening. I also made sure I was mid-void on the actual screening (I did my homework). I think that's probably all the relevant information. Thanks.

Your home tests and immunassay tests usually have a cutoff of 50ng for thc. The GC/MS should have a 15ng cutoff. Thats why idf your on prescription drugs you know its going to get the tougher confirmation test of GC/MS. Depending on your thc level you will be screwed. Thats why alot of here advocate synthetic urine.

But does a positive test have to be positive for both EMIT and GC/MS? What if I'm negative EMIT and positive GC/MS?

If you tested positive for your prescription for adderall it will automatically get sent to GC/MS. And then they'll will find anything you've taken in the last 3 or 4 days except for thc which will still be there for a month or more depending on intake levels.

Yes it does.

It doesnt work that way. Labs will not run a confirmation GC/MS on a urine sample that tested negative on the initial EMIT screen. It would be a big waste of time and most importantly, money. GC/MS testing is not cheap. It must be understood that labs are like any other business - they are in to making a profit and they are not going to run unnecessary tests which could eat away at their bottom line.

If a urine sample tests negative on the initial screen, the testing is over then as a "passing" status.

^^^Thanks for the semi-clarification Burnt. I guess what I was trying to ask in retrospect was if the GC/MS test gets run only to confirm a "specific" drug, or to simply retest the sample at a higher sensitivity level. I was worried that since I would test positive for amphetamines and negative for weed and opiates on the EMIT, that my sample would get sent to the GC/MS and would come up positive for the weed and opiates. I wasn't sure if I would get screwed in that way.

However, I got the call from the lab today and I only tested positive for the adderall. I told them the prescription information, and got a negative result. I can't believe I didn't get a "positive dilute" result since I drank soooo much water and gatorade before the test and didn't take in any creatine. And I don't know if my sample got sent off to GC/MS or not. But I'm off! I would call KillerWeed a douche for scaring the shit out of me, but I'm too happy with the result to care. I hope my experience proves helpful to others in the future.

Even though you're clear now I just want to add that I'm pretty sure the further testing is just to see HOW much of that amphetamine was in your urine and if that is a medicinal dosage then it's alright. If it's too high to be medicinal then you'd be screwed. Also opiates like codeine would be alright anyway since they are OTC.

Gotta read site rules again. We do not discuss ANY other drugs here. And we certainly don't call names while we're doing it.
