Laboratory & Specialised Testing
Laboratory Confirmation
When an onsite drug or alcohol screening test returns a non-negative result, laboratory confirmation may be required. NQDD arranges confirmation through NATA-accredited laboratories.
Who this service is for
Employers, legal professionals and individuals who require confirmation of a non-negative onsite screening result.
How it works
- 1An onsite screening test returns a non-negative result.
- 2The sample is secured and sent to a NATA-accredited laboratory.
- 3The laboratory performs confirmation analysis.
- 4Confirmed results are reported confidentially.
Compliance & confirmation
An onsite non-negative screening result is not a confirmed positive. Only laboratory confirmation by a NATA-accredited laboratory can confirm a positive result. Laboratory accreditation belongs to the partner laboratory, not to NQDD itself.
Why choose NQDD
- Secure chain-of-custody for samples
- NATA-accredited laboratory pathways
- Clear reporting of screening versus confirmed results

Frequently asked questions
What does a non-negative onsite result mean?+
A non-negative onsite screening result means the screen indicated a possible substance. It is not a confirmed positive and requires laboratory confirmation.
Who is accredited for laboratory confirmation?+
Laboratory accreditation (including NATA accreditation) belongs to the partner laboratory. NQDD itself is not NATA accredited.
How long does laboratory confirmation take?+
Turnaround times depend on the laboratory and the substance being confirmed. NQDD can provide current guidance on request.
