If you are using Quick Fix (2oz.), be aware that 2oz. is the exact amount needed by the lab. And the lab is also aware that Quick Fix is 2oz. The collector might be trained to ask for more than the line on the cup. This is a way to catch you. Or they can wait for you to come out, and say "Oh, two ounces exactly?" and dump it and ask for more.
2 oz is enough sample for any U/A. The collector may ask for more, only to discard the excess. Under DHHS regulations, the collector has to accept the sample if 2 oz is all the donor can submit.
DOT tests require only 45 ml of sample. The sample is then split 30/15.
Burnt Toast Reviewed by Burnt Toast on . Dr Greens Agent -X and LabCorp Worked Felt obligated to share my recent experience submitting Dr Greens Aget X 7.0 to LAbcorp for a preemployment Urine drug Screen. Sample was submitted at 930am at Labcorp on Wed May 12th. Heard back from HR dept on Mon May 17th at 230pm I passed and assigned start date. So that is four days. I am guessing that the negative results were given to new employer before the four business days thats just when I heard the good news. I did learn a lesson or two, and felt it worth my time to share Rating: 5
