When employers invest in workplace drug testing, they want confidence in the results. They need a testing process that is fair, accurate and able to stand up to scrutiny if questions arise. That’s where a NATA laboratory comes into play.
What is a NATA laboratory? In simple terms, it’s an independent laboratory that has been assessed and accredited to perform testing to strict national and international standards.
For workplace drug testing, this accreditation provides an important layer of quality assurance. While modern on-site screening can be extremely accurate, any non-negative result should be confirmed by a NATA accredited laboratory before it is considered a positive result.
Who is NATA?
NATA stands for the National Association of Testing Authorities, Australia. It is Australia’s leading accreditation body for laboratories, inspection bodies and testing facilities.
Rather than carrying out testing itself, NATA assesses laboratories to ensure they consistently meet strict technical and quality requirements. Accredited laboratories must demonstrate that they:
- Use validated testing methods.
- Employ qualified and competent staff.
- Maintain calibrated equipment.
- Follow strict quality management systems.
- Produce accurate, repeatable and reliable results.
Regular assessments ensure these high standards continue to be maintained.
What makes a laboratory a NATA laboratory?
For a testing laboratory to be a NATA laboratory it must have successfully met the demanding accreditation requirements highlighted above.
When a sample is sent to a NATA accredited laboratory, employers can have confidence that the testing has been performed using recognised scientific procedures and rigorous quality controls.
For workplace drug testing specifically, this is vital. These laboratories are responsible for confirming the presence of drugs in samples when an initial screening test indicates a possible detection. Employers and employees are relying on the process to be reliable and accurate. And by using a NATA laboratory, everyone can be confident the confirmation process ensures this.
Why are NATA laboratories necessary for workplace drug testing
No on-site screening technology should be relied on to provide the final legal determination of a positive drug test.
Instead, workplace drug screening on a worksite is conducted to identify employees who may have drugs in their system. It’s looking for results that are non-negative. Any non-negative result is then sent to a NATA accredited laboratory for confirmation.
This approach provides speed, accuracy and fairness.
Employees are not unfairly labelled as having returned a positive result based solely on a screening device. Instead, the laboratory independently confirms the finding using highly sophisticated analytical equipment.
This process also provides employers with confidence that decisions affecting employees are based on verified scientific evidence.
Is on-site workplace drug screening inaccurate?
If workplace drug testing non-negative results need to be confirmed by a NATA laboratory, does this mean on-site testing isn’t accurate?
Not necessarily. While it can depend on the technology used, on-site screening can be very accurate.
For example, at Integrity Sampling, we use Dräger drug and alcohol testing equipment for all workplace testing. This equipment is recognised worldwide for its quality and reliability. Independent evaluations have shown our Dräger drug testing equipment is greater than 99% accurate, making it one of the most precise screening systems available.
However, no screening technology is 100% accurate. That’s why Integrity Sampling follows industry best practice.
This means a workplace drug test is not considered positive until a non-negative screening result has been confirmed by a NATA accredited laboratory. This protects both employers and employees by ensuring every confirmed positive result has undergone independent scientific verification.
Why this matters for employers and employees
Employers have legal and ethical responsibilities when managing workplace safety. Making decisions based on inaccurate information could have significant consequences for both the organisation and the employee.
Using a workplace drug testing provider that follows recognised best practice helps organisations:
- Improve workplace safety.
- Support fair treatment of employees.
- Reduce the risk of disputes.
- Increase confidence in testing outcomes.
- Ensure testing follows recognised Australian standards.
When laboratory confirmation forms part of the testing process, employers can demonstrate they have taken reasonable steps to ensure the accuracy of their decisions.
It also matters for employees because no one wants to receive an incorrect positive result.
The confirmation process helps ensure that only scientifically verified results are reported as positive. This gives employees confidence that the testing process is objective, independent and fair.
It also reinforces trust in workplace drug and alcohol testing programs.
Choosing a workplace drug testing provider
Not every workplace drug testing provider follows the same procedures.
When selecting a provider, employers should ask important questions such as:
- Is high-quality screening equipment used?
- What happens if a screening test is non-negative?
- Are samples sent to a NATA accredited laboratory for confirmation?
- Does the provider follow recognised Australian workplace testing procedures?
- Can the provider explain the complete testing process?
When you choose Integrity Sampling, you can be confident you’re partnering with a professional workplace drug and alcohol testing provider that follows industry best practice. We combine highly accurate Dräger screening equipment with independent NATA laboratory confirmation, ensuring transparency, accuracy and reliability throughout every stage of the testing process.
