What is the acceptable temperature range for a urine specimen at the time of collection?

The acceptable temperature range for a urine specimen at the time of collection is indeed between 90°F to 100°F (32°C to 38°C). This range is critical for ensuring the integrity of the specimen. A temperature within this range indicates that the urine is likely fresh and has not been tampered with or substituted, as urine that comes from a human body typically falls within this temperature range shortly after collection.

Testing the temperature of the specimen is an important step in drug testing procedures to help verify that the sample is valid. If the temperature falls outside of this specified range, it may raise suspicions about the authenticity of the sample and could lead to further investigation or re-testing.

In contrast, the other options either set the temperature range too low or too high, which does not align with the physiological norms for fresh human urine. This misalignment would compromise the credibility of the urine specimen in a testing context.
