Urine sample collection procedures need to strike a balance between trusting clients and ensuring that specimens are not contaminated or falsified. Many programs use temperature strips to make certain that urine specimens are produced on site and are body temperature.
When it comes to temperature, DOT Rule 49 CFR Part 40 Section 40.65 (What does the collector check for when the employee presents a specimen?) reads:
(b) Temperature. You must check the temperature of the specimen no later than four minutes after the employee has given you the specimen.
(1) The acceptable temperature range is 32–38 °C/90–100 °F.
(2) You must determine the temperature of the specimen by reading the temperature strip attached to the collection container.
(3) If the specimen temperature is within the acceptable range, you must mark the “Yes” box on the CCF (Step 2).
(4) If the specimen temperature is outside the acceptable range, you must mark the “No” box and enter in the “Remarks” line (Step 2) your findings about the temperature.
(5) If the specimen temperature is outside the acceptable range, you must immediately conduct a new collection using direct observation procedures (see §40.67).
