With creatinine and S/G checks becoming lab SOP in recent years, sample color became the least aspect in determining an overly-diluted sample. Even samples with a nice yellow color to them can still be ruled "too-dilute" due to low S/G and creatinine levels.

Therefore, when utilizing dilution techniques, it is now more important to make sure the creatinine and S/G are within satisfactory ranges - more important than "coloring" of the urine.
Burnt Toast Reviewed by Burnt Toast on . question about specific gravity hi all...thanks for the extremely informative posts. there's a lotta misinformation out there that this board could help clear up. i took a drug screen yesterday (UA, eCup) -- beforehand, i used a home kit to test my first void and passed with a decent enough line. i drank a 20-ounce gatorade, plus a sip or two of orange juice, about an hour or so before the test, both so i could successfully void on time and as a little extra insurance. at the lab, my urine was not quite completely clear, Rating: 5
