Product as listed by the FDA

TCube One Step Multi-Drug Oral Fluid Test Cube (AMPSO,COC20,METSO, OPl40,OXY20,THC2S) Product Usage: T-Cube¿ One Step Multi-Drug Oral Fluid Test Cube is a rapid oral fluid screening test. The test is a lateral flow, one-step immunoassay for the qualitative detection of specific drugs and their metabolites in human oral fluid at the following cut off concentrations for use in employment and insurance testing. The assay provides a qualitative, preliminary test result. A more specific analytical method must be used in order to obtain a confirmed result. Gas Chromatography/Mass Spectrometry (GC/MS) or Liquid Chromatography/Tandem Mass Spectrometry (LC/MS-MS) are preferred confirmatory methods. Professional judgment should be applied to any drug test result, particularly when preliminary results are positive.
