DOT 5 panel drug test programs normally test for SAMHSA 5 drugs. They only use onsite or offsite services with SAMHSA Certified Labs that are regulated by the DOT. 5 panel drug test kits screen for the SAMHSA 5 drugs and can be used by businesses not required to follow regulations set up by the DOT. 5 panel drug test kits are also available in other 5 panel drug configurations. If you are looking to perform a DOT 5 panel drug test onsite or offsite, you are at the right place. See more about our DOT 5 panel drug test kits and services below.
