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 dilution as I had a cup of coffee and 1 bottled water. So I keep testing myself at home which I pass every attempt (2 more of the test from Walgreens & a few strips purchased from another store).
So my test for the job was coming up on May 28th at a Concentra facility which sends out the UA to Advanced Toxicology Network. At this point I have passed 3 at home drug test (Walgreens) and three strips since May 21st so I believe that I am in the clear. One test even used the first void of the day which also showed as negative. I failed my drug test for the job on the 28th and thought that the job must have had a lower cutoff level such as 20ng/ml or even 15ng/ml. Needless to say I have been bummed out since.
The MRO called and told me THC showed up on the drug test and I was so shocked I was speechless at the time. The at home test gave me a false sense of security. So I call the MRO back the next day and one of the assistants tells me that the positive result showed 62ng/ml of THC in my urine.
Here's my question: if the at home test has a cutoff of 50ng/ml and I pass 3 of them with the first passed result a week before the real UA, how was my level of THC at 62ng/ml?
When I called the MRO back I assumed I would have been told the THC level was below 50ng/ml then I would have known the job was testing at a lower level. I do not understand why my results showed the 62ng/ml even though I was passing the at home tests that cutoff at 50ng/ml. Can someone please help me understand the results.
Because at this moment I do not have any faith in the at home test and people saying if you pass those you should be all good. Thanks in advance for any responses.
