Final answer:
The temperature of a NIDA urine specimen must be taken within 4 minutes to verify sample validity, reflecting body temperature.
Step-by-step explanation:
The temperature of a NIDA specimen collection of urine must be taken within 4 minutes after collection to ensure the sample's validity. This is a regulatory requirement to confirm that the urine sample is fresh and hasn't been tampered with or substituted. The temperature range should typically be between 90°F and 100°F. Within this timeframe, it's possible to get an accurate reading that reflects the body temperature of the individual at the time of urination, ensuring the sample's integrity.
