If you do somewhat frequent random urine drug testing (at home or workplace) these drug tests are great since they are affordable, accurate and easy to administer. For convenience we would recommend getting the premium full sets that come with the gloves and cups or even more convenient Cup Drug tests. If you are concerned about possible adulteration we would recommend you to get either separate adulteration tests or use cup based drug test kits that have add-on adulteration with our urine drug test kits.
Saliva drug testing kits are very easy to administer and donor friendly. So they make great drug tests to be used as on the job random drug testing or reasonable suspicion drug testing.

For employee drug testing, if you want to determine current use or impairment, saliva drug tests are the best.
