Havn't smoked since March 30th. Taking a preemployment drugtest.

I'm skinny as hell, 152 Lbs, 6'0 tall.
Been running like 5 or 6 times in April. like 30 minutes each time.

Gotta take a Labcorp urine test here in the next couple weeks.

On the labcorp site it has this document:
http://www.labcorp.com/pdf/doa_reference_guide.pdf

it says that the "Labcorp standard screening cutoff level" is 50 ng/mL
then it has "Labcorp standard GC/MS confirmation cutoff level" is 15 ng/mL

Is that saying that they will only use GC/MS if the standard one comes up positive?

Also, what are my chances of passing if i use dolution/ don't use diloution (i'm scared they will know the creatine or gravity levels are off)

I'm plannin on runnin tonight and every day for the next 3 or 4 days because i'm scared again.

I also took a at home test for thc April 13th , caught the first urine of the day and it showed a very faint line which is 'passing' according to the test.

This job is really important and huge. thanks

I would think that if you havent had any MJ in the last 30 days you should be fine, especially the fact of your weight and metabolism seem to be working in your advantage. However I would recommend that you order a few home test strips just to be on the safe side. You can find them on Ebay or at your local Walgreens. They are fairly inexpensive and pretty reliable. When testing yourself make sure to use the beginning stream of urine from your first piss of the day and if you can pass with a bold line you can pass the UA from labcorp. There are other methods if you are still uneasy about using your urine such as substitution which have very good results and is very easy to pull off. Check the threads for substitution on this site by using the search tool.

Sorry I forgot to mention the fact that if you are going to use your own urine I wouldnt dillute and be sure to cut the excercise a few days before taking the test as THC metabolites are stored in your fat cells and burning fat isnt a good idea right before the test. Also start eating larger meals with little to no activity as this will put your metabolism on storage mode(Hence the reason we have so many morbidly obese people here in the US). Also please visit the proper forum after your test results to help others with techniques and other variables that will help us all get a better understanding of MJ and how to avoid testing positive.

Just means that the screen is the dipstick at 50 ng/ml. If you fail, they do a gc/ms where the cutoff is 15 ng/ml. But that doesn't mean the test is at a lower cutoff. They only test for one species in the gc/ms, which correlates pretty well to the 50 ng in the immunoassay (50 ng) test.

Good luck.
