I guess what I was really trying to ask is in your opinion would the amount of fluids consumed (36 ounces) in the time frame they were consumed (1 hour 45 min) lower my S/G and creatinine levels enough to cause a diluted/invalid test.
There would be no way of knowing this without knowing what your "baseline" creatinine and S/G levels were prior to diluting - and youre not going to know this either without testing your creatinine and S/G with a validity test kit. Without testing, all thats left is a bunch of guesswork. And around these parts, we have zero faith in guesswork and speculation, particularly when careers, families, and freedoms depend on the outcome of a drug test.
