Bought a used car? Taking over a rental? Sending your team into an unfamiliar space?
If you’ve ever wondered “what’s actually on these surfaces?” — we can tell you.
We provide certified fentanyl testing for vehicles and buildings across San Francisco, Los Angeles, San Jose, Long Beach, Oakland, Sacramento, and most of California.
Fentanyl is 50 to 100 times stronger than morphine. A trace amount the size of a few grains of salt can be dangerous.
And it doesn’t go away on its own. Residue can sit on a steering wheel, carpet, or wall for months until someone properly removes it.
You can’t see it. You can’t smell it. You have to test for it.
Cars, trucks, vans, fleet vehicles, and rideshares can all carry residue without any visible sign.
Common reasons people call us:
We sample the spots that matter most — steering wheel, seats, vents, carpets, console, and any hidden compartments — then send everything to an accredited lab.
Buildings have more surface area and more porous material, which means more places for residue to hide.
We test:
Soft surfaces like carpets, curtains, upholstery, and HVAC systems are the biggest culprits. A property can look spotless and still test positive.
Tell us the situation.
Certified techs, proper PPE, no drama.
Results from an accredited facility.
Clear answers, plus next steps if anything's found.
If it’s clean, you have documentation. If it’s not, we’ll walk you through what to do.
If anyone shows these symptoms, call 911 immediately and give naloxone (Narcan) if you have it.

Common questions about Fentanyl Testing.
Indefinitely. It doesn’t break down on its own — without proper decontamination, residue can sit there for months or years.
Home strips test drug samples, not surfaces. For real answers — and documentation that holds up legally or for insurance — you need certified sampling and lab analysis.
On-site sampling usually takes under an hour for a vehicle. Lab results typically come back within a few business days.
We’ll explain your options. Most properties can be decontaminated and re-tested to confirm they’re safe again.
