Ok my bad then.

Thanks for your response, that's good to know. I'm not sure what the Creatinine level was like I said and frankly I'm not sure the Concerta clinic I'm going to does either, since they sent the lab off to ATN. I'm hoping not obviously. The chain of custody/lab requisition forms don't say anything to that effect at all. Either way I think my regular ol' piss will be good but I'm really hoping to sub.
