Testing Process

Supplier: LaneWorkSafe

The most common way to test for drugs is a urine test. This involves giving a urine sample which is then either immediately screened through a dip screen or sent for full laboratory analysis. The initial screening informs the testing officer whether the donor has traces of drug in his/her body or not.

Testing Process

The urine test procedure is fully supported by Australian Standard AS4308:2008.As with any screening there is a small error rate, however, if the initial screening is conducted in accordance with the manufacturer's instructions the results are approximately 99% accurate.

A breath test is used to determine the amount of alcohol a donor has in his or her system. The principal of breath analysers is based on Henry's Law, which states that the concentration of gas in the air immediately above a liquid is proportional to its concentration in liquid.

There are various situations when your employer may ask an employee to take a drug test. These include:

  • Pre-employment Tests: To decrease the chance that a current drug user will be hired, some employers test job applicants at the time of a job offer. The job offer being dependent on a negative drug test result.
  • Random Testing: To discourage drug use amongst all employees, and in some cases to comply with industry legislation, an employer may ask employees to take drug tests at random and unpredictable times.
  • Post-Accident Testing: An employer, and in some industries law enforcement officers, may test employees who have been involved in an accident, near accident or detected unsafe practice to establish if alcohol or other drugs use may be an issue.
  • Return to Work: Where an employee has to take a form of leave due to be being detected for alcohol or other drugs abuse he or she must show clean test results prior to being permitted to return to work.
  • Refusal: A refusal by an employee to a lawful request to submit for an alcohol or other drugs examination is treated the same if the employee returned a positive result.
