Principle: Test to determine dilution of a urine sample. The test field contains a creatinine indicator, which reacts in an alkaline medium to form a brown colour complex.
Evaluation: Creatinine originates from creatine phosphate in the organism. It is proportional to the muscle mass of the individual and is excreted through the kidneys in near constant amounts. In accordance with the DOT – Guidelines, a urine sample containing less than 20mg/dl creatinine is considered diluted and thereby manipulated.
