I recently took a pre-employment drug test at LabCorp using the dilution method and the results came back as 'Dilute.' I spoke with HR and they said just come in on Moday, get another form, go back to LabCorp and take another test. So today I went out and bought QF and plan on using that for my upcoming test. I just have a two questions:

1. The test requires a split-specimen so I'm not sure if the 2oz. is going to be enough. Would there be any problems if I added just enought of my own hyper-dilute urine to be safe?

2. Is the lab going to compare my dilute sample with the new specimen?
