What are the differences between the oral fluid tests and the urine drug tests?
An oral fluid drug test involves the use of a swab to collect saliva in the mouth and gums. The test does not require a restroom and the testing procedure can be administered right at your location. A urine drug test comes in a variety of formats, such as dips, pipettes, and cups. The iCupĀ®, for example, has built-in adulteration tests available to check the validity of a urine sample.
