      When a sample comes back with the creatinine levels below the cutoff (usually 20mg/dl) in addition to the “specific gravity” being off…dont ask me to explain the gravity thing cause I dont really understand how that part works.

        Specific gravity is just the density of the sample divided by the density of water. The dissolved salt and urea make it more dense so the closer the specific gravity is to 1, the closer it is to being water.

      If you dilute the piss you put in for a drug test it won’t register anything- most test labs will also reject it for that reason
