I understand that the B-Vitamin is primarily to keep the urine a more "normal" color, and not look so diluted. However, what prevents the sample from seeming diluted when they test it? Or is that why you drink electrolytes to raise the specific gravity, because then the sample doesn't seem dilute? I'm just wondering how they determine whether or not dilution was done because for my pre-employment screen dilution is counted as an automatic positive so I dont want to encounter that.
