AMPHETAMINES IN ORAL FLUID BY LCMS/MS

Oral fluid (saliva) drug testing detects recent drug use — typically within 24-48 hours — and is collected under direct observation, making it difficult to adulterate or substitute. LC-MS/MS testing provides specific identification and quantification of amphetamine, methamphetamine, MDMA, and related compounds.

This test is used in workplace drug testing, treatment monitoring, and clinical assessment when recent use is of interest. The shorter detection window can be either an advantage (focuses on recent use) or limitation (won't detect use from days ago) depending on the clinical purpose. Sample type is oral fluid.
