All you need to know about lab tests

How long does it take to have a drug test?

It usually takes between 10-15 minutes, depending on a number of factors such as the time taken to answer any questions, complete the paperwork, for the person to pass urine, and whether the sample needs to be sent to the laboratory for further testing. The drug screening test itself takes up to 5 minutes.

When will I know the results of my drug test?

All test results are sent to the laboratory for review and checking by trained laboratory staff to ensure the accuracy and quality of the results. A report will be emailed to the address provided at the time of collection within 24 hours. Please note that should the specimen be referred for further laboratory testing the results of this testing will be reported following completion of the additional testing.

Who has access to my results?

The results of the test will be reported as a secure PDF document, by email, to the person(s) designated at the time of collection. Altmed also retain a copy of all results.

What do I need to bring along with me when I have a drug test?

You will need to bring photo identification such as a valid Driver Licence, Passport or Site Safe ID.

Should I have a lot to drink before my drug test?

It is recommended to have had a drink of water or other beverage in the 2 hours leading up to your drug test. Drinking too much may over-dilute your sample, causing the integrity checks to fail and may mean that another sample is required. You should also avoid going to the toilet an hour prior to your drug test to ensure you are able to provide an adequate sample for testing.

How often can I be drug tested?

How often you can be required to undergo a drug test usually depends upon your employment contract and the policies at your workplace. It often depends on the role you have in the workplace and the risks associated with that role.

How much notice does my workplace have to give me that I will be having a drug test?

Your workplace is not required to give you any notice unless your specific employment contract and workplace policies state otherwise.

In what situations in my workplace can I be required to have a drug and/or alcohol test?

The circumstances around your drug test may vary according to your company policies and procedures. It is becoming increasingly common for potential new employees to be required to undergo (and pass) a pre-employment drug screening test. Once employed by a company, drug and/or alcohol testing may be required in the following situations:

  1. Random testing
  2. Post-incident testing
  3. Reasonable cause testing
  4. Rehabilitation
  5. Pre-employment/pre-contract
  6. Internal transfer

What drugs are you testing for?

The onsite drug screen tests for 6 different drugs and/or their metabolites. These include; cannabis (THC-COOH), amphetamine, methamphetamine, cocaine metabolite, opiates and benzodiazepines.

Do you test for alcohol?

How long does it take to get my results back from the lab?

Laboratory results are generally available 24-72 hrs following the receipt of the sample at the laboratory.

Can you tell if someone tries to cheat their drug test?

Yes, there are a number of ways of determining whether or not someone has tried to cheat their drug test.

Do you keep a database of people who fail their drug tests?
