Principle: Determination of the dilution of a urine sample. The test involves the ionic concentration of the urine. In the case of falling ionic concentration, a colour from yellow (high density) to green, to blue green (low density), results.
Evaluation: The normal value for adults with average nutrition and liquid intake lies approximately between 1.015 and 1.025. In accordance with the DOT – Guidelines, urine is considered diluted when in addition to a creatinine content of less than 20 mg/dl, the density is less than 1,003.
