Imitator, this is from the big bad book of protocols drug test collectors must follow:

Subpart E - Urine Specimen Collections

§ 40.65 What does the collector check for when the employee presents a specimen?
As a collector, you must check the following when the employee gives the collection container to you:
(a) Sufficiency of specimen. You must check to ensure that the specimen contains at least 45 mL of urine. (1) If it does not, you must follow ??shy bladder? procedures (see §40.193(b)).
(2) When you follow ??shy bladder? procedures, you must discard the original specimen, unless another problem (i.e., temperature out of range, signs of tampering) also exists.
(3) You are never permitted to combine urine collected from separate voids to create a specimen.
(4) You must discard any excess urine.
(b) Temperature. You must check the temperature of the specimen no later than four minutes after the employee has given you the specimen.
(1) The acceptable temperature range is 32??38 °C/90??100 °F.
(2) You must determine the temperature of the specimen by reading the temperature strip attached to the collection container.
(3) If the specimen temperature is within the acceptable range, you must mark the ??Yes? box on the CCF (Step 2).
(4) If the specimen temperature is outside the acceptable range, you must mark the ??No? box and enter in the ??Remarks? line (Step 2) your findings about the temperature.
(5) If the specimen temperature is outside the acceptable range, you must immediately conduct a new collection using direct observation procedures (see §40.67).
(6) In a case where a specimen is collected under direct observation because of the temperature being out of range, you must process both the original specimen and the specimen collected using direct observation and send the two sets of specimens to the laboratory. This is true even in a case in which the original specimen has insufficient volume but the temperature is out of range. You must also, as soon as possible, inform the DER and collection site supervisor that a collection took place under direct observation and the reason for doing so.

Your story sounds suspect because they should have made you provide a second sample anyway and not just "well it was 92 and I failed."
