thanks, BT -- i was actually hoping you'd reply. so if i'm understanding your reply correctly, a lab technician may not necessarily examine a sample and think "oh, this appears to be diluted, let me send it to the lab for further testing". rather, it's a matter of whether or not it gets sent to the lab in the first place, unless the eCup technology/tester is sophisticated enough to successfully detect creatinine or S/G levels. and i doubt there's anyone with enough knowledge of the ecup/ereader technology to definitively say.

the conclusion i'm drawing here is that the 20-ounce gatorade, unless i am extremely unlucky, will not be enough to trigger a negative-dilute result. does that sound about right?

thanks again. i am approximately 90% positive that i am fine, based on the negative home test with the first void and the fact that i drank what amounts to a normal-sized beverage. but one never knows.
