Following positive screening for muscle relaxants, definitive confirmation testing identifies the specific medication(s) present — such as carisoprodol, cyclobenzaprine, or methocarbamol. This is essential for distinguishing prescribed use from misuse and for clinical and legal decisions.
This test is used in pain management compliance monitoring, workplace and forensic testing, and clinical situations requiring definitive identification. Sample type is urine, often under chain-of-custody protocols.
