8 Panel Drug Tests provide a comprehensive screening solution for organizations that require broader drug detection beyond basic panels. Building on standard testing, these panels typically include substances such as Amphetamines, Cocaine, Opiates, PCP, and THC, along with additional drugs like benzodiazepines, barbiturates, or methadone—depending on the specific configuration. Larger panel tests expand coverage to identify both illicit and commonly misused prescription drugs.
