What happens if a drug test is invalid due to temperature?

When a drug test is deemed invalid due to temperature issues, it’s important to ensure the accuracy and integrity of the testing process. Temperature is a crucial factor because it can indicate whether the specimen is genuine or has been tampered with. If the temperature falls outside the acceptable range, this is a sign that the sample may not be reliable for testing.

In such cases, the correct procedure dictates that a second specimen must be collected. This ensures that the testing process can continue and that a valid sample can be obtained for accurate analysis. Collecting a second specimen allows for the necessary checks and balances to verify the initial results and confirm the individual's drug use status without relying on a potentially compromised sample.

The other choices do not address the need for ensuring the validity of the test. Dismissing the test or only sending the first specimen without further action would compromise the integrity of the results. Thus, collecting a second specimen is the appropriate and required response in scenarios where the temperature of the first specimen is out of range.
