I had my pre employment UA today at around 9:00am. I drank about 32oz of water at 6:00am and voided about 4 times before my UA. By the time I went to void for the UA, my urine was a normal looking yellow color. I'm being a worrywart, but that amount of water should not dilute my test results, correct?
Theres no telling. That would depend on what your baseline S/G and creatinine levels were before you consumed the 32 oz of water.

Creatinine and S/G are checked at the labs to determine samples that are too diluted. This measure had become SOP in recent years. Therefore sample "color" became the least aspect in determining dilution. Even samples with a nice yellow color to them can still be ruled "too dilute" due to low S/G and creatinine levels.
