They may be good at collecting pee and blood, but this lab and the Quest network is poorly setup. Do not trust any of the information that is on the website or what these people tell you. Was in here twice and they couldn't perform the DOT drug tests that they have advertised on their web page or on the Quest Collection website.
Additionally, the people here sent me to another location to get the test done and that location could not do it. This lab and the Quest network appear to be undermanned and unable to figure out what they really do. Don't know if I would risk your screening to this group if they can't manage to do these little things correctly.
Find a different lab to take care of your family and employees.
