Drug Screen Panels

Please help !! I would like to know the complete information about the types of Panel in the drug screen test and the types of drugs tested in the respective panel. How is it counted like it is a 10 panel or a 12 panel drug test? Sometimes there would be stuffs like creatinine which is not supposed to be counted for the Panel number. Which are the stuffs need not be counted? Please help or provide me a good link where I can find all.. Thanks a lot for your help !!!
talk to the lab. They might have advice

Google search

You talking uds? I know what my hospital looks for, yours might be different. Call the lab. If this is generic, try googling.
