The temperature of a urine sample should be within which range for it to be usable in a drug test?

The correct range for a urine sample temperature to be considered usable in a drug test is typically between 32° to 38° C (90° to 100° F). This temperature range is important because it ensures that the sample has not been tampered with or substituted.

When a urine sample is collected for a drug test, the temperature is checked immediately after collection. A temperature below 32° C may indicate that the sample is old or has been contaminated, while a temperature above 38° C might suggest the sample was heated for adulteration purposes. Maintaining a temperature within the 32° to 38° C range helps ensure the integrity of the sample and the accuracy of the drug testing results.

The other temperature ranges provided are either too low or too high, falling outside the accepted standards for urine samples intended for drug testing.
