What Is a 12-Panel Drug Test?
A 12-panel drug test in Mesa shouldn't feel like a hurdle. Our walk-in lab screens a single urine sample for twelve different classes of commonly tested substances—including the prescription opioids most nursing programs and healthcare employers require. Here's what we test for:
Amphetamines: Including amphetamine and methamphetamine—prescription stimulants like Adderall as well as illicit speed.
Cocaine: Identifies cocaine metabolites from powder cocaine or crack.
Opiates: Screens for codeine, morphine, and heroin.
Phencyclidine (PCP): Detects this illicit hallucinogenic substance.
THC (Marijuana): Identifies cannabis metabolites from marijuana use.
Benzodiazepines: Detects prescription anti-anxiety medications and sedatives like Xanax or Valium.
Barbiturates: Identifies central nervous system depressants used in sedatives and seizure medications.
Methadone: Screens for methadone, used in pain management and recovery programs.
Propoxyphene: Detects prescription narcotic pain relievers in this class.
Methaqualone: Identifies older-generation sedative-hypnotic substances.
Oxycodone: Detects prescription opioids including OxyContin, Percocet, and Roxicodone—a key addition required by most healthcare and nursing program panels.
Fentanyl: Identifies synthetic opioid use, including prescription fentanyl patches and illicit fentanyl—critical for healthcare worker screening.
Instant 12-Panel Screen vs. Lab-Based 12-Panel
While the terms are frequently used interchangeably in casual conversation, a rapid drug screen and a lab-based confirmation represent two entirely distinct levels of laboratory science.
Instant 12-Panel Drug Screen: Your fastest option for same-day answers. A reliable preliminary yes-or-no result is available within 15 minutes
Lab-Based 12-Panel Drug Test: Uses LC-MS/MS technology at our SAMHSA-certified laboratory partners — the gold standard in drug confirmation. This sophisticated process precisely measures the exact levels of each substance in your system, giving you definitive, quantitative results—not just a yes-or-no answer. Secure results delivered directly to your patient portal within 24–48 hours.
Same price either way — choose the tier that fits your timeline.

12-Panel Drug Test FAQ
What does a 12-panel drug test look for? A 12-panel drug test covers all ten substances found in a standard 10-panel test—amphetamines, barbiturates, benzodiazepines, cocaine, marijuana, methadone, methamphetamines, basic opiates, PCP, and propoxyphene—but adds two more specific drug categories. It checks for expanded prescription opioids (like oxycodone and Percocet) and expanded stimulants (like Ecstasy/MDMA).
How fast do you get 12-panel drug test results? Because our clinic offers same-day results on our clear rapid tests, you can walk out the door with your initial paperwork in hand. If a test is clear of all tracked substances, standard laboratory results are typically uploaded straight to your secure online account within 24 to 48 hours. If a sample requires a secondary laboratory confirmation check to rule out a false positive, it takes 2 to 3 business days.
What's the difference between a 10-panel and a 12-panel drug test? A 12-panel drug test screens for everything in a standard 10-panel — plus two additional prescription opioids: Oxycodone (OxyContin, Percocet) and Fentanyl (synthetic opioid). Most healthcare and nursing programs specifically require these added substances to be tested, which makes the 12-panel the preferred option for medical and healthcare worker compliance.
