What is the acceptable temperature range for a urine sample during drug testing?

The acceptable temperature range for a urine sample during drug testing is between 32° to 38° C (90° to 100° F). This range is critical because it helps to ensure that the urine sample is freshly produced and has not been tampered with or substituted. The body temperature of a healthy individual typically falls within this range, which makes it a reliable indicator that the sample is genuine.

Collecting and analyzing urine at this temperature range allows for the effective screening of substances while reducing the likelihood of false results. Samples that fall significantly outside this temperature range could indicate fraud, such as dilution or substitution, making the temperature check an essential step in the integrity of urine drug testing protocols.

In contrast, other ranges listed do not align with the physiological norms of human body temperature, which is why they are not acceptable for drug testing purposes. Maintaining the standard within the 32° to 38° C range ensures the validity of the testing process.
