Which drug classes are typically included in a standard UDT panel?

• A. Opioids, Cocaine, Barbiturates, Methadone, Z-drugs
• B. Amphetamines, Opioids, Cannabinoids, Cocaine, Benzodiazepines, PCP
• C. Cannabinoids, MDMA, Ketamine, GHB
• D. Alcohol, Nicotine, Caffeine, Acetaminophen

Answer: (B)

Urine drug testing panels focus on the drug classes most commonly abused or misused, so a standard panel is built to detect those broad categories. The typical six-drug class panel includes amphetamines, cannabinoids, cocaine, opiates, benzodiazepines, and PCP. This combination covers stimulants, cannabis, cocaine, opioids, sedative-hypnotics, and a dissociative hallucinogen, which are the substances most often screened in routine workplace or clinical testing. Other options introduce substances not usually part of a standard panel: barbiturates and methadone or Z-drugs aren’t consistently included in the basic panel, and alcohol, nicotine, caffeine, and acetaminophen aren’t the targets of a standard urine drug screen. While some labs offer expanded or specialized panels, the six-class panel described is the typical baseline.
