Who uses this panel
Today's most common expanded cup for pain clinics, MAT programs, corrections and cautious employers.
What candidates should know
Methadone maintenance patients show steady-state levels constantly — clinic programs EXPECT positivity and monitor take-home compliance via EDDP ratios.
Employment 10/12-panel cups include MTD; a documented opioid-treatment-program prescription verifies through the MRO and is protected in many jurisdictions.
Its long, variable half-life (8–59 hours) makes personal prediction unreliable; clinic supervision governs dosing.

Absence from a panel means absence of testing — not safety. Specialty orders, expanded cups, probation panels and sports programs reach further. If your situation involves court supervision, treatment programs or safety-sensitive certification, assume wider coverage.
