We perform testing on-site for our clients. This is usually done for scheduled random testing and unscheduled after hours testing most commonly done for post-accident or reasonable suspicion.

We were summoned to a local manufacturing plant to perform a post-accident drug and alcohol test after hours on one of the plant supervisors. As is customary, we first performed the breath alcohol test with no incident. Following that the donor gave multiple excuses as to why he was unable to urinate, realizing we weren’t leaving he finally produced a specimen about an hour later.

We recently had a female donor come it to our clinic for a urine drug test. She made her first attempt but was unable to produce enough urine to be tested (we need 45ml, about 2 ounces). We gave her a bottle of water and sent her back to the waiting room while we attended to other people testing that day.

She wasn’t there long when she shot up out of her chair with her pants soaking wet and abruptly left the building. Apparently she had a “clean” specimen of urine hidden on herself somewhere and the container it was in broke spilling the urine all over herself.

It is Federal Regulation that we must maintain a “bluing” agent in the tank and bowl of any commode used for urine drug testing. The reason is so that donors cannot attempt to substitute water from the commode as their urine specimen or use that water to “dilute” their urine.

It is much harder for a lab to detect drugs in a specimen that has been diluted by either adding water to the specimen or if the donor consumes large amounts of water/liquid.

Just when you think you’ve seen everything you get surprised!!

The most common way a cheater tries to defraud a drug test is by bringing “clean” urine with them and hiding it on their body somewhere. They then pour the clean pee into the collection cup while in the bathroom. When this happens at First Choice Drug Testing our collector does not accept the specimen. Standard protocol (for non-federal test) is to discard the urine and allow them to “try again”. We had a cheater try 5 different times to thwart our collector with urine that obviously did not come from her body, she must have had a pint of pee on her.
