This 12-panel screen uses enzyme immunoassay for initial detection of multiple drug classes — typically including amphetamines, benzodiazepines, barbiturates, cannabinoids, cocaine, methadone, opiates, oxycodone, PCP, propoxyphene, and other commonly tested substances. Presumptive positives undergo LC-MS/MS confirmation for definitive identification.
This test is widely used in pain management compliance, addiction treatment monitoring, workplace drug testing, and forensic applications. Sample type is urine, often under chain-of-custody protocols.
