The appropriate thermal vary of a urine specimen collected for substance abuse screening is a essential consider figuring out its validity. This vary is often 90-100F (32-38C) when measured inside 4 minutes of voiding. A deviation from this established vary raises suspicion of adulteration or substitution of the pattern.
Sustaining the integrity of urine samples by way of temperature verification affords a number of advantages. It serves as a deterrent in opposition to people trying to govern take a look at outcomes. Moreover, it supplies a stage of confidence within the accuracy of the testing course of, defending each the person being examined and the group requiring the screening. Traditionally, the implementation of temperature monitoring has coincided with a lower in reported situations of pattern tampering.
