The Acon Panel Drug Test comes in One, two, three, four, five, six, eight, nine and 10 panel drug test configurations. Acon Panel drug tests feature multiple test configurations with simultaneous rapid results and instant detection of the presence of multiple drugs of abuse. Acon multi drug test kits are based on the principle of the highly specific immunochemical reactions of antigens and antibodies which are used for the analysis of specific compounds in human urine. The Acon Panel Drug Test is intended as an initial forensic screen for the presence of drug or drug metabolites at the time the test is performed. It is important to know, that our multi drug test comes with a built-In control that tells you if the test is working or not. Multi (multiple) just means that you can test for more than one drugs at the same time simultaneously, and the test will display the results all at one time.
