How to action a sample that does not register a temperature
When performing urine drug testing there are a number of integrity checks that need to be completed, including checking the temperature of the urine specimen.
The collector (testing officer) should check the temperature of the urine specimen as soon as the donor hands over the specimen — within 4 minutes of the collection. The acceptable temperature range is 33°C to 38°C.
If the temperature is within the acceptable range, document it in the relevant section of the Chain of Custody (COC) form and proceed with the collection procedure.
If the temperature is outside the acceptable range
The sample cannot be accepted. Follow this procedure:
- Clearly note the reason at the top of the COC form: “Note – COLD SAMPLE” or “Note – HOT SAMPLE”.
- In the Description of Sample section on the COC, write “No temperature registered – COLD SAMPLE” or “No temperature registered – HOT SAMPLE”.
- Complete the collection process for the first specimen and immediately request a second collection.
- Inform the collection site supervisor that a collection took place where no temperature was detected and that a further collection has been requested.
After the repeat test or tests are collected, all specimens are forwarded to the laboratory for drug and specimen integrity testing. Every specimen is uniquely labelled and accompanied by its own chain-of-custody form, and a record is entered in the permanent record system for each collection.
