Specific gravity in relation to a drug test is one of the more important measurements when it comes to proving that you don’t have any drugs in your system.  Specific gravity has everything to do with proper kidney function.  Testing for specific gravity will indicate if there is a problem with your kidneys. The kidneys are set up to help clear the human body of different water-soluble molecules which include various toxins and metabolic waste.  This metabolic waste is what may get you in trouble in a urine test.  THC and other drug metabolites are filtered through the kidneys to be excreted through the urinary tract. The kidneys concentrate the urine so that harmful toxins can be removed from the body.  This urine concentration is known as specific gravity.  Testing for specific gravity does not limit itself to dilution but can also reveal health problems like diabetes and chronic urinary tract infections which may go undetected otherwise.

The first step in a urinalysis is a visual inspection by the tester.  A normal urine sample is a pale yellow to a darker yellow color and is usually clear.  A cloudy sample can be caused by excessive protein in the sample or the crystallization of salts in the provided sample.  An abnormal color in the urine sample like a dark brown or amber color may indicate the presence of hemoglobin or myoglobin in the urine, the presence of a food dye in the sample or even as simple as just eating fresh beets.
