Drug Screening

Frequently Asked Questions

I believe most people are good at heart. Why should we bother testing if they have a good interview?

99% of the time you are probably right.  Some people are dishonest.  The safer thing to do is to check, then you know you have done everything you can.  Besides, by checking, it is one more layer to protect you from exposure and liability in the case of a bad hire.


Do I need to have a random drug testing procedure in place?

We can’t answer that for you.  You know your business and the risks that go along with that.  We recommend it for most, but you have to decide.



What is Adulteration?

The intentional tampering with a urine sample by the donor to avoid detection of illicit drug use.  Successful adulteration produces a false-negative test result.  We provide STAT products that will detect adulterants in human urine.
