Today I had a preemployment drug screen at a labcorp location. I was under the impression that labcorp would require at least 45ml to be split into two samples (one sample of 30 and another of 15). When the lady handed me the little cup and pointed to the 15ml line saying that was the minimum, it threw me for a loop! I subbed using Quickfix and I'm freaked out about this. I gave them 30 ml. What does this mean??

I think it means they only wanted 15 mls! Too bad you gave her 30, you should have saved the rest of your quickfix! Are you thinking the collector made a mistake? I would seem to think that as much collection as they do this would be a huge error, so big that the collector would catch it. If you have the test codes, go to their website and look up the code and see if it tells you how much of a sample is required.

No, not at all. She knew what she was doing. It just seemed to me that if the volumes aren't what I've been studying on this messageboard and others, then the test may be different too. Maybe i'm just paranoid!

So what do y'all think the chances are that I passed? There was no suspicion, the lab lady was super nice...she called me 'baby' several times. Does the 15 ml mean they sent it to gc/ms?? Any responses would be much appreciated.

From reading the boards, they only give samples the gas that turn up positive. If the assay gets a neg line and the integrity is okay (creatine, specific gravity, etc.) your Quick Fix sample should be fine.

 

Sec

15 mL is not enough to do both an immunoassay AND a GC/MS. Also, there is none left over to confirm at a second lab (split specimen). Your EMPLOYER is probably only doing an instant type of test with no laboratory confirmation.

I don't know how many times it takes, but I will say it again...

The laboratories do not dictate whether a test is observed or not, the quantity of the specimen, what type of testing is done; etc.
100% of those decisions are made by the EMPLOYER. The laboratory and/or the collection facility only ensure that the collection is done according to regulations (or employer protocol in the case of non-regulated employers).

LabCorp (MedTox, Kroll, ATN, LabOne, Quest, etc...) can do an instant only test using any configuration of anywhere from 1 to 10 panel (types of drugs tested for) or a 3-panel, 4-panel, 5-panel.......10-panel immunoassay with GC/MS for any quantity of cut-off amount set by the employer. The reason so many different employers use the same cut-off levels and the general 5 or 10 panel tests is because that is what is recommended by the labs an those tests have the lowest pricing (best value for the employer).

Any questions?.... good.

Yes..... but I am afraid to ask. You typed that with such authority you scared me.

The Custody form just says "10 panel". Based on the above response, I guess that just means 10 different drugs are tested for using an immunoassay with no confirmation. The test was Thursday afternoon and I didn't hear anything on Friday. If I passed and got the job, I need to tell my boss as soon as possible that I'm leaving. Do y'all think I'd be safe to do this Wednesday morning if I don't hear anything during the day on Tuesday (Monday is a holiday)?

If I had come up positive for anything, would a MRO have called me to try to figure out if there were any legitimate reasons why I was a positive?

I also wanted to add that the labtech lady didn't write any observations on my form like I've read that others get. She just wrote a couple of numbers. She tore the sheets apart and told me that one was for my employer and the other was for me. Is this significant at all?? Wondering and worrying about these results is going to drive me crazy this weekend.

Reading this makes me glad I work for a company that has both corporate and USDOT testing programs - I'm only subject to corporate because I don't have a CDL, drive a truck etc... but the procedures are nearly identical to my knowledge, other than corporate doesn't do a split sample, and they usually don't do a breathelizer alcohol test. What I mean is the Urinalysis is the same collectors w/ the same rules.....

seems like USDOT testing is pretty standardized.

also one more thing I noticed they were checking for temp 90-100 - one thing I read is USDOT is that, but some company tests look for 94-100 - but not mine they wanted 90. If you can't hit 90-100 when subbing u deserve to fail
