7 DRUG PANEL (BARBITURATES, COCAINE, CANNABIS, OPIATES, AMPHETAMINES, BENZODIAZEPINE, METH)

The 7-drug panel is a screening test detecting barbiturates, cocaine, cannabis (THC), opiates, amphetamines, benzodiazepines, and methamphetamine in urine, blood, or saliva. Detection windows range from 1–30 days depending on the drug and usage. Used for employment, legal, or medical purposes, it provides qualitative results with cutoff levels (e.g., 50–100 ng/mL) and requires GC-MS confirmation for positives. Factors like metabolism and hydration influence results.2s

The 7-drug panel is a standard drug screening test that detects the presence of seven commonly abused substances in urine, blood, or saliva. The panel typically includes:

Barbiturates: Sedative-hypnotics used for anxiety or sleep, detectable for 2–7 days.
Cocaine: A stimulant, detectable for 2–4 days (up to 2 weeks for heavy use).
Cannabis (THC): Psychoactive compound in marijuana, detectable for 2–30 days depending on usage.
Opiates: Includes morphine, heroin, and codeine, detectable for 1–4 days.
Amphetamines: Stimulants like Adderall, detectable for 1–3 days.
Benzodiazepines: Sedatives like Valium or Xanax, detectable for 1–7 days (up to 6 weeks for long-acting types).
Methamphetamine (Meth): A potent stimulant, detectable for 1–5 days.

Purpose: Used for employment screening, legal cases, or medical evaluations to identify recent drug use. Results are typically qualitative (positive/negative), with cutoff levels (e.g., 50–100 ng/mL) to minimize false positives. Factors like metabolism, hydration, and test sensitivity affect detection windows. Confirmation with gas chromatography-mass spectrometry (GC-MS) is standard for positive results.
