5 quick tips to help you to start onsite drug & alcohol testing in your workplace

There are many advantages to doing your drug and alcohol screening in house as it can save your company a lot of time and money. Staff do not need to attend a testing centre which keeps costs down and time away from work to a minimum.

Here are 5 quick tips to help you get started

  • Be prepared-make sure that you have everything in place before you begin. It is advisable to have a drug and alcohol policy for your workplace, in place before you start testing. You will also need consent forms, onsite drug testing kits, and ideally a lab chain of custody confirmation drug test pack.
  • Make sure you have a clear protocol to work to and decide who is going to do the testing, and that you have a clear management plan for any non negative results.
  • You will only need to confirm non negative results
  • Make sure that you have the ability to confirm any non negative results obtained with onsite drug testing kits with a laboratory chain of custody confirmation test. Best to have at least one of these onsite when you begin testing.
  • Keep clear records of all results & ideally have everything witnessed

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.

Standard drug test panel combinations for the UK and EU employment drug testing tend to be THC, COC, AMP, MET, MOP

THC = Cannabis 50ng

COC = Cocaine 300ng

AMP= Amphetamine 1000ng

MOP = Opiates 300ng

MET = Methamphetamine 1000ng

With drug use on the increase in under 16 year olds in the UK, worried parents are turning to home drug test kits to identify specific drug problems in their teenagers.  Consumers are able to purchase a variety of testing kits which will identify if drug residues are still present in either saliva or a urine sample.
