What temperature range suggests that a specimen may have been adulterated?

The identification of potentially adulterated specimens relies significantly on the temperature readings of urine samples. A reading below 90°F or above 100°F is particularly telling. If a urine specimen is below 90°F, it is often too cold to be considered a valid sample from a typical human body temperature range, suggesting it may have been tampered with or substituted. Conversely, a specimen above 100°F may imply that heat has been applied to either alter its natural state or impede detection methods.

This temperature range serves as a red flag in the testing process, guiding collectors to further investigate the integrity of the sample. Hence, a specimen that falls under these temperature readings typically warrants additional scrutiny or possibly even rejection for testing.
