The First Sign Drugs of Abuse Test Kit, manufactured by Hemosure, is a 6-panel dip card test for the detection of various substances in urine. This one-step test utilizes a competitive immunoassay process. Antibodies in the test card compete with drug molecules in the urine sample. The presence of a specific drug can prevent antibody binding, indicating a positive result. The test detects AMP (amphetamines), BZO (benzodiazepines), COC (cocaine), mAMP/MET (methamphetamine), OPI (opiates), and THC (tetrahydrocannabinol, the psychoactive compound in marijuana). Includes user instruction and 25 individually pouched dip cards.
