Why do they use urine test for most drug testings?
Companies that contract us to do their drug testing use urine test because its the fastest and cheapest for them. We have companies inquire about the hair and saliva test, but since we only have urine testing equipment for our company we have to outsource the hair and saliva test. When they see the quote for one test they always stay with the urine test. Though we do have a few contracts that use saliva and hair, we just collect the samples and send it off to a company that can process the test for us.
