I don't know but kb gave me a random drug test and the lady broke the tab as she was closing the lid,safety told me it could come back diluted and would have to retake test but they didn't put any hold on me.
Well, unless the bottle was placed in a bag full of water, there was nothing to dilute the sample. The tab being broken was an issue and you probably should have requested that the person use another bottle. Other than leaking out of the bottle, there was nothing that would have interacted with the sample.
I got a diluted once. They told us the doctor would be there in about an hour for our drug tests. I already had to go but an hour I could wait. Three hours later and I'm about to lose my mind I've got to piss so bad. Told the lady holding us in the room it wasn't an option anymore and I had to go. I went to the bathroom and come back and she says I have to be able to urinate when the doc gets there because they don't want to wait on me. So I chugged as much water as possible and then the test came back diluted. Take another test the next day, no problems. Diluted tests are nothing to worry about if you're clean.
Im not positive but I believe the second sample will undergo a different kind of testing the gas method and you should be OK after that is done.
