EMTECH Multi-Drug 5 Dip Card (AMP/MOP/THC/MET500/BZO) uses the principle of lateral flow immunochromatographic assay that detects the presence of metabolites of Amphetamine (AMP), Morphine (MOP), Tetrahydrocannabinol (THC), Methamphetamine (MET) and Benzodiazepine (BZO) qualitatively in human urine. This test is only used for screening and cannot be used to monitor drug levels. The gold standard that can be used to determine analyte levels is Gas Chromatography/Mass spectrometry (GC/MS). EMTECH Multi-Drug 5 Dip Card (AMP/MOP/THC/MET500/BZO) uses the principle of competitive immunoassay between related drug metabolites in urine samples with conjugate antibodies. For in-vitro diagnostic use only.
