Killerweed, in your opinion, if I take no B-12 before my test, and my pee has some natural yellow in it, will this generally be an acceptable sample, meaning not too dilute. I have been doing some experimenting today with dilution, and I am trying to get this down to a science.

When people fail for being too dilute, can we assume their pee is completely clear (taking into account they haven't taken any B-12)?
From what I've read on here, if your going to a lab, the color isn't *that* important. It seems to be more important with the home tests or PO tests. Not saying you shouldn't do it, but from what I've read all it does is change the color. In most lab tests, it will still get checked for creatinine clearance and specific gravity regardless. (So your urine could be clear as long as those levels are right and its a pass, or your vitamin yellow and your creatineine and sg is off causing a fail/dilute.) I'm pretty sure i have that right, I'm quoting off FBR's many posts.

I guess that answers your question is that you can't assume its diluted on color alone because it could still have the proper specific gravity and creatinine clearance. That can only be proven with a labtest. I could be wrong, but I'm pretty sure I'm correct on that.
