Drug Test Panels & What They Test For

Every goMDnow panel in one table — the exact drugs screened by specimen type, from the federal DOT 5-panel to extended 14–16 panel screens with fentanyl.

Panels by specimen type

Drugs shown in orange are what each panel adds beyond the standard five (Amphetamines, Marijuana/THC, Cocaine, Opiates, PCP).

Urine Panels Detection window: ~1–5 days for most drugs · specimen validity checks (creatinine, pH, nitrite) included on every panel.
Specimen Type Panel Drugs Included
UrineDetection: ~1–5 days for most drugs 5 Panel DOT Amphetamines (amphetamine, methamphetamine, MDMA, MDA) · Marijuana (THC) · Cocaine · Opioids (codeine, morphine, 6-AM/heroin marker, hydrocodone, hydromorphone, oxycodone, oxymorphone) · Phencyclidine (PCP) The federal panel required for all DOT-regulated tests under 49 CFR Part 40.
5 Panel + FEN (DOT-style) All DOT 5 Panel drugs · Fentanyl Fentanyl is not part of the federal panel; this configuration is ordered as non-DOT.

Orange = drugs added beyond the standard 5-panel.† = final analyte list confirmed on the lab requisition at order.

What is specimen validity testing?

Lab-based urine panels automatically check creatinine, pH, and nitrite levels. These aren't drugs — they're integrity checks that detect dilution, substitution, or adulteration of the sample, so employers can trust a negative result.

Hair and oral fluid collections are observed, which is why those specimens don't require the same validity markers.
