The normal temperature of human urine ranges from 94Â°F to 96Â°F (about 35 Â°C). The temperature of drug test sample must be measured during first 4 minutes after it was received, as it changes depending on ambient temperature. Acceptable range is from 90 Â°F to 100 Â°F (32 Â°C - 38 Â°C) , any sample with a temperature out of this range will immediately fall under suspicion. Container cups for the samples also usually have a built-in thermometer that registers the temperature of the piss as soon as it enters the container.
1 Given that urine is mostly water, but also contains some other substances dissolved in the water, its density is expected to be close to, but slightly greater than, 1.0. 2  This is true-the density of normal urine is in the range 0.001 to 0.035. 3  Approx.4  95% of the volume of normal urine is due to water. Recognition and analysis of abnormalities of urine can provide information about the condition of the body. 2  Biochemical analysis of urine is called urinalysis, and is commonly used to diagnose a wide range of diseases. 3  Typical volume of urine: 1-2 litres / 24 hours per day (normal adult).
