Choosing a method
Urine vs oral-fluid vs hair follicle
The three methods have different applications and detection requirements. We encourage you to discuss the correct testing method with NQDD.
Urine Screening
Application
Generally indicates recent use over a broader detection window
Collection method
Onsite urine sample collection
Standard reference
AS/NZS 4308:2023 where applicable
Oral-Fluid Testing
Application
Generally indicates very recent use
Collection method
Onsite oral-fluid (saliva) sample

Hair Follicle Testing

Laboratory methodology dependent
