The ExperTox unknown drug panel screens for a broad range of substances depending on the selected panel size. It detects common drugs of abuse such as opioids, amphetamines, cocaine, cannabinoids, and benzodiazepines. Larger panels include additional synthetic drugs, designer compounds, and less common metabolites. Basic panels focus on common drugs like THC, cocaine, and opioids. Expanded panels add synthetic cannabinoids, fentanyl analogs, and designer stimulants. Comprehensive panels cover hundreds of substances, including emerging drugs. PANEL SIZE ## How does panel size affect what the ExperTox unknown drug panel screens? Panel size directly determines the range and number of substances detected. Smaller panels cover fewer drug classes and substances, focusing on the most commonly abused drugs. Larger panels expand coverage to include new synthetic drugs and metabolites, increasing detection capability. | Panel Size | Typical Substances Screened | | --- | --- | | 5-10 substances | Common opioids, cannabinoids, cocaine, amphetamines, benzodiazepines | | 20-50 substances | Includes synthetic cannabinoids, fentanyl analogs, designer stimulants | | 100+ substances | Extensive coverage including emerging synthetic drugs and metabolites | Choosing the right panel size depends on testing goals and the substances of concern.

For DOT testing, the urine protocol is mandatory. PANEL SELECTION ## How do I choose the right ExperTox unknown drug panel size for my needs?
