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?
OF is enough according to law, Just tell them as you come out thats all you could go. Tell them you were afraid to drink too much because of the last time results. You can dilute yourself as a back up but thats about it. Thats enough for a split sample. adding your dirty urine defeats the purpose of subbing. If your worried and it's important buy a second bottle but they will dump it anyway.

No to your second question.
