About fentanyl residue
Fentanyl is far more potent than heroin, which is why it is handled with care. Medical toxicology guidance indicates that brief skin contact with residue is very unlikely to cause an overdose; the greater risks are visible powders that become airborne and accidental ingestion, particularly by children.
Fentanyl contamination in Australian homes is much less common than methamphetamine, but testing is warranted where there is a known history, a police seizure or unexplained powders.
Where we sample and why
- Storage areas, safes and cupboards
- Benches and tables used to cut or package drugs
- Bathrooms and bedrooms where drugs were used
- Vehicle consoles, glove boxes and boots
If you find powders, pills or drug paraphernalia, do not touch or clean them. Leave the area and call police. If anyone is drowsy, has slow breathing or pinpoint pupils, call 000 immediately.
How we test
- We discuss the history of the property or vehicle and agree which substances to target.
- A technician takes measured wipe samples from high-risk and general surfaces, photographing each location.
- Samples go to a NATA accredited laboratory under chain of custody for targeted analysis.
- Our hygienist interprets the results and you receive a report with locations, results and next steps.
Multiple drugs can be tested from one visit. Methamphetamine sampling is covered by our NATA accreditation (No. 20837). For substances without a specific Australian residential guideline, results are interpreted against the national clandestine laboratory guidelines and the circumstances of the property.
