50 ng, 20ng, 15 ng pre emp UA - thoughts and experiences

[SensiGirl]

10 panel test this week

test is a "medtox" test, 10 panel, but no other info given re: 50, 20, 15. don't know if i'll get a form in advance

anyone have experience with medtox? on the website it suggests 50ng but

I imagine it is up to the employer - paranoid b/c they will not hire people who smoke and now i am thinking why wouldnt they test for the lowest limit possible

i'm cool on a 50 ng c/o, but have no way of knowing whether i would pass anything lower

thoughts? suggestions? (aside from subbing- i have my concerns there too, cuz i am a nervous nelly if you can't tell)

SensiGirl,

Breathe...and relax....I have been a basket case as well and all it is doing, is nothing;My start date is next Monday and I already put my two weeks in so I feel your pain.(little pep talk) I've subbed a few days ago (QF)and still waiting. When is your test? This crap sucks I recommend to anyone quiting 4-6 months before you ever start your job search.


I did post about PCC/Oxidants and found others had the same result on thier home intergrity tests and still passed the lab tests.

Search for "Quick Fix 4.0 Oxidants/PCC" in google. there is another site just like this one. And follow this persons posting trail and you will see this person passed and found the same results I found with the integrity strips. He was freaking as well.


Although I do not have the answers right now...I did feel like you needed someone to calm you down.


As for what method I am not the expert but ones who is experiencing your pain.

It appears that for the GC/MS test they will test at these levels. For the standard immunassay test the cutoff should be 50.

i know. i am freaking out. just finished 45 mins on the treadmill, trying to sweat and speed up the metabolism.

thing is, i dont know if i am at 48 ng, 45ng, 30ng, 20, whatever - just that i am not testing + at 50 ng.

subbing scares me because of my job and being caught could mean trouble

i quit for 2 mos, told i did not get the job. smoked 4-5 "hits" (not even bowls) 10 days ago - should be tested weds thurs or fri (trying to push it back)

i am just wondering if i can dil. to a level below 20ng, answers anyone? i would imagine.

also, killer, i thought about that too, that the 20 ng was for a "second test", because it says "this analysis", but can't tell for sure. poorly worded, that is for sure.

here is their website. i will call tomorrow and ask what that means. i looked at the other panels, and tried to compare if the thresholds are for the second test, or the 'drug screen' by immunoassy. hard time telling.

MEDTOX : Test Catalog

[SensiGirl]

OK, i just called and asked

guy told me that 20 ng is the cut off for thc on the "screen" meaning the IA

however, he told me that this is not the best test for workplace testing and the employment catalog is not online, the test i was looking at was a clinical drug test and not a forensic test.

a nonregulated test can have a c/o of 100ng, 50ng or 20 ng with a gc/ms confirmation of 15, 1 or 5.

i still have no idea what level my test will be at. most likely 50 ng with the possibility of 20 ng


so, killer, deige, FBR, Tebit, and the powers that be, even if it is 20, in your opinion, how are my chances with dil. given the info above?

[Deige]

How many days clean are you? Are you passing your home tests without diluting?

[SensiGirl]

thanks deige

today is 10 days, and before that i was 60 days clean and had tested clean at 50ng after a glass of water after 39 days

10 days ago - 5 small hits (super nice stuff) over a 4 hour period

by test time will be 13-15 days clean, with 60 days before that

tested clean today - not first void (but would never give that anyway)

had a cup of coffee and an 8 oz glass of juice. so no heavy dilution, just normal drinking and the third or fouth void of the a.m.

no asprin either.

not worried about 50ng, worried about 20ng
