This is a drug residue test for Benzodiazepines. It is called a colorimetric assay that detects Benzodiazepines, often called ‘Benzos.’ This simple on contact test contains two analysis papers suitable for two to four independent trials. The results appear as a color change by wiping the analysis paper on a suspect article or surface and adding a drop of liquid from the ampoule.
