Frequently Asked Questions
What shows up on a 10-panel drug test?
A standard 10-panel test screens for: Marijuana (THC), Cocaine, Amphetamines, Opiates (codeine, morphine), Phencyclidine (PCP), Benzodiazepines, Barbiturates, Methadone, Propoxyphene, and Quaaludes. Some labs substitute expanded opioids or synthetic cannabinoids for outdated substances.
How long do drugs stay in your system?
Detection windows vary by drug and test type. Urine tests typically detect: Marijuana 3-30 days (depending on usage), Cocaine 2-4 days, Opiates 2-4 days, Amphetamines 2-4 days, Benzodiazepines 2-14 days. Hair tests detect 90 days of history. Individual metabolism and usage patterns affect detection times.
Can I fail a drug test from secondhand smoke?
While unlikely, it is possible to test positive for marijuana from extreme secondhand exposure (e.g., enclosed car with heavy smokers). Standard cutoff levels are designed to avoid false positives from incidental exposure. If you believe you have a false positive, request a confirmation test.
What happens if I fail a drug test?
For employment tests, a positive result typically means the job offer is withdrawn for pre-employment screening, or disciplinary action for current employees. Medical Review Officers (MRO) contact you to verify if there's a legitimate medical explanation (prescriptions) before reporting to employers.
How accurate are drug tests?
Laboratory drug tests are highly accurate. Initial screening tests have low false positive rates. Any positive screening result undergoes confirmation testing using GC/MS (gas chromatography/mass spectrometry), which is considered the gold standard with near 100% accuracy.
Do I need an appointment for drug testing?
Walk-ins are welcome at most locations, but appointments are recommended to minimize wait time. Same-day appointments are usually available. Some specialized tests (like hair testing) may require appointments. Bring valid ID and any required forms.
