Accurate Testing for One of Today’s Most Dangerous Drugs
Fentanyl is a synthetic opioid up to 50 times stronger than heroin and 100 times stronger than morphine. While it is legally prescribed for severe pain, illicit fentanyl is often mixed into other drugs without the user’s knowledge — a combination that can be deadly in microgram amounts.
Test Smartly Labs in Kansas City includes fentanyl detection in our advanced drug testing panels, helping employers, legal entities, and individuals identify fentanyl use quickly and accurately.
Why Fentanyl Testing Matters
Because fentanyl is potent in such small doses, even trace exposure can cause:
- Respiratory depression and unconsciousness
- Seizures or cardiac arrest
- Death within minutes without intervention
Fentanyl is frequently mixed with heroin, cocaine, meth, and counterfeit prescription pills, often without the user’s knowledge. Standard drug panels may not detect fentanyl unless specifically included — that’s why we offer drug panels that specifically screen for fentanyl in addition to other substances.
Who Should Consider Fentanyl-Inclusive Drug Testing?
- Employers in safety-sensitive industries who want comprehensive screening
- Parents concerned about potential substance use in teens or young adults
- Legal cases involving child custody, probation, or pre-trial monitoring
- Treatment centers monitoring clients during recovery
- Post-accident and reasonable suspicion workplace testing
- Community organizations responding to opioid overdose trends
How Fentanyl is Included in Our Drug Panels
At Test Smartly Labs in Kansas City, we offer customizable drug panels that can include fentanyl along with other substances like marijuana, cocaine, amphetamines, opioids, and synthetic drugs.
We can test fentanyl in:
- Urine – Most common method for workplace, legal, and personal testing
- Hair – Detects patterns of use over the past 90 days
- Blood – Used for recent exposure confirmation
- Oral fluid (saliva) – Convenient and non-invasive, detects recent use
- Nails – Provides a long-term drug use history
Our laboratory partners use sensitive and specific immunoassay screening followed by confirmation via GC/MS or LC/MS-MS technology to ensure reliable results.
When You’ll Receive Your Results
- Negative results – Often available within 1 business day
- Non-negative results – Require lab confirmation, typically within 2–5 business days
All results are handled with strict confidentiality and can be reported directly to authorized individuals or entities as required.

Before testing:
- Bring a government-issued photo ID
- Complete TSL Intake Form & HIPAA Disclosure
- Pay for your test on the day of service (we do not bill insurance but provide documentation for self-claims)
- Arrive 3 hours before closing for urine testing to allow time for collection
- For hair or nail testing, make sure hair is dry and nails are clean (remove polish or artificial nails)
