Thanks again for your response, Toast. I get everything your saying and it is all correct. But by passing the home test without diluting (again diluting a home test serves no purpose) on more than one occassion had me believing I would pass the lab test. By getting the quantative result from the GC/MS means it was sent there for confirmation for the failed initial screening. Based on my home tests results I should have passed that initial screening. If I failed the lab initial screening I should have failed the at home test but I passed 3 of them with the first on May 21st. My lab test was May 28th (a week later).

So there is no way the company I was trying to work for had a lower cutoff level than 50ng/ml for their initial test?

Here is my brief story with a couple of questions to follow: I was daily smoker and I understand how the levels of nanograms per milliliter (ng/ml) build up on one's body. So I stopped smoking on April 29th with my last hit the previous night around 9pm. I started taking the at home drug test from Walgreens about 3 weeks later. I failed the first one which I thought I would but assumed I was getting close to the cutoff level. I passed my first at home test on May 21st around 11am with no Rating: 5
