Does THC Show Up on a 10-Panel Drug Test?
Evidence-based answer reviewed against SAMHSA cutoffs and FDA assay documentation · Updated September 2026
Quick answer: Yes. A 10-panel drug test includes THC (screened around Urine immunoassay screens for the metabolite THC-COOH at 50 ng/mL (initial) with GC–MS confirmation at 15 ng/mL (SAMHSA workplace standard).).
What a 10-panel drug test actually tests for
Here's the full drug list with typical urine cutoffs:
| Drug class | Typical urine cutoff |
|---|---|
| THC | 50 / 15 |
| Cocaine | 150 / 100 |
| Opiates incl. heroin | 2000 / 2000 |
| Amphetamines | 500 / 250 |
| PCP | 25 / 25 |
| Barbiturates | ~250–300 |
| Benzodiazepines | ~300 / 200 |
| Methadone | ~300 / EDDP |
| MDMA | 500 / 250 |
| Propoxyphene/propoxyphene (legacy) | ~300 |
| THC | ✅ Detected |
Who uses this panel
The default 'general workforce' panel for many non-DOT employers — everything DOT tests plus depressants and ecstasy.
What candidates should know
Urine drug tests do not look for active THC. They look for THC-COOH, an inactive metabolite your liver produces after you consume cannabis in any form — flower, vape carts, dabs, or edibles. Because the metabolite is fat-soluble, it lingers far longer than the high itself, and there is no reliable way to predict an individual's exact clearance time from a chart.
Edibles and smoked cannabis produce the same THC-COOH metabolite, so a test cannot tell how you consumed it. Concentrates such as dabs deliver larger doses of THC, which tends to extend the detection window rather than shorten it.
Delta-8 and THCa products are chemically different from delta-9 but are converted to the same metabolites after use. Most workplace panels cannot distinguish them, so 'hemp-derived' labeling does not make a product test-safe.

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.
