Urine Drug Testing FAQ | How to do a urine drug test

Undertaking drug testing for the first time can be a daunting task, but the basic procedure is very simple.

An initial urine sample is collected and brought to room temperature (usually 20 minutes) The sample is then tested using a standard panel combination drug test. The cut off levels for drug test panels is internationally agreed and traditionally work to SAMHSA and NIDA levels for urine analysis.

Professionally produced and batch certified drug testing urine kits are between 97 and 99% accurate when compared in studies to laboratory drug screening using GC/MS methods. This level of accuracy is considered by all bodies as high enough to be acceptable for all negative onsite drug test results.

In simple terms, if the instant drug test result is all normal, and the sample collection and procedure are all acceptable no further action need be taken.

Confirming all positive results is essential in a workplace situation. No further action should be taken before laboratory GC/MS confirmation of a positive result is obtained.

Where employment drug testing is part of a occupational risk assessment for a high risk occupation, the employee should not be allowed to perform this task pending the confirmation result, but no disciplinary or penalty action must be taken by the employer before absolute confirmation is obtained.
