Identification Of Methamphetamine and Amphetamine in Drug Abuse Urine Sample using Multi-drug Rapid Test and Gas Chromatography-Mass Spectrometry (GC-MS) at the Centre of Drug Testing Laboratory, National Narcotics Board Republic of Indonesia

Drug abuse is a real threat that threatens the Indonesian nation in the form of non-military threats. The second most abused illicit substance in the world is methamphetamine (MA). Most of the methamphetamine users in the world live in East and Southeast Asia. Methamphetamine is a powerful stimulant of the central nervous system (CNS) that can make someone feel an increase in sympathomimetic. First, the preliminary test was conducted using a BioCare multi-drug rapid test and a specific methamphetamine rapid test that works based on the Lateral Flow Assay (LFA) principle. Second, the sample preparation used Liquid-Liquid Extraction (LLE). Third, GC-MS confirmed the test using GC-MS Shimadzu-QP2020NX-GC-2030 (HP-5MS column, Length 30 m, diameter 0.25 m, film 0.25). The Preliminary test shows that the urine is positive and contains methamphetamine and amphetamine. Based on the sample chromatogram, There are 2 peaks, which are methamphetamine and amphetamine compounds it can be seen by the retention time is 5.560 minutes (methamphetamine) a similarity index of 98% to methamphetamine compounds, and 4.885 minutes (amphetamine) with a similarity index of 96% to amphetamine compounds. The urine samples with code 210DGB from methamphetamine users were detected due to the presence of methamphetamine and amphetamine, which is the metabolite of methamphetamine.
