My first instinct is both, in case something goes wrong (temp isn't right, etc.). However, the only person I know I can get a clean sample from is my pregnant wife. I'm hesitant to use her sample, not because she's pregnant or she's a female, but that I've read pregnant women have much lower creatine (or creatinine) levels than normal. I've been taking a creatine supplement since yesterday, but don't want to have her take any (it's really too late anyway from what I understand). And I've never subbed before, so it makes me nervous as hell.

I've got temp strips and am getting a bottle today to use for subbing, but would feel so much better if I could be confident in diluting. Check my results in the attachment and let me know what you think. I know a line is a line is a line, but if the attendant has poor eyesight, they might not see this line. This comes from my first void of the morning. I plan on testing my dilution method (as per the sticky, minus the aspirin, plus the gatorade) and re-test. If it comes up neg, should I be okay? The test is at a doctor's office, not a corporate lab like Quest (I don't know if that makes a difference).

Gotta get this job. I sincerely appreciate any help you all can offer. Thank you, this board has a huge amount of helpful information.
I understand your fear about the faint line. I myself have also wondered the same thing about the tech that's testing the sample and their ability to recognize a line. But immunoassay tests, home or lab do not calculate quantitative values. They only produce a positive or negative test result, so faintness shouldn't be a factor.

As far as the creatine levels in pregnant women.. I'm not for sure on this, but I'm sure one of our other experts will help you. I could really see you going either way on this one. I saw a faint line on your test result, so I'm gonna say that a light dilution would be sufficient for you to pass.
