COCAINE BY LCMS/MS

After use, cocaine is rapidly metabolized to benzoylecgonine, which is detectable in urine for 2-3 days in occasional users and longer in chronic users. LC-MS/MS testing quantifies both the parent drug and metabolite with high specificity.

This test is used to confirm presumptive positive screens, support clinical assessments in addiction medicine, monitor treatment compliance, and provide medico-legal documentation. Sample type is urine.
