Does Gabapentin Show Up on a 16-Panel Drug Test?
Evidence-based answer reviewed against SAMHSA cutoffs and FDA assay documentation · Updated August 2026
Quick answer: Depends on configuration. Gabapentin appears on some 16-panel cups depending on manufacturer and program.
What a 16-panel drug test actually tests for
Here's the full drug list with typical urine cutoffs:
| Drug class | Typical urine cutoff |
|---|---|
| 14-panel list | above |
| Kratom (mitragynine) + synthetic cannabinoids (K2/spice) dedicated strips | assay-dependent |
| Gabapentin | ❌ Not detected |
Who uses this panel
Modern maximum-coverage cup used by treatment programs and some probation systems.
What candidates should know
Gabapentin isn't on standard employment panels. Pain clinics, MAT programs, and some probation systems monitor it specifically because of abuse-potential findings — those orders use dedicated assays.
Renal excretion is nearly complete and unchanged, giving it one of the cleaner pharmacokinetic profiles among monitored drugs.

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.
