On the urine drug test, there is a temperature strip. The purpose of the temperature strip is to ensure that the liquid in the test is in fact urine by measuring its temperature. When urine is eliminated from the body it will be at the donor’s body temperature between 36.1°C to 37.2°C. Hence, if the specimen is not within this temperature range it is unlikely that it is urine or does not belong to the donor.
Checking the temperature of the specimen is the first thing you should inspect on the urine drug test.
Additional safeguards are also in place to ensure that the specimen is in fact urine.
