Urine Collecting Process
When you undergo a urinalysis drug screen, you are directed to a nearby collection site, typically a private bathroom or bathroom stall and no personal items with you. The donor then produces and deposits the urine specimen into a specially designed secure cup and handed directly to a technician. They may perform initial testing immediately on site or seal the specimen with tamper-resistant tape, typically in your presence, and package it for transport to the lab for testing.
Detecting Synthetic Urine
People will attempt to sneak fake urine into the collection site, resulting in part of the drug testing process of urine samples to be the adulteration check. This test is done to determine whether the specimen is genuine and not synthetic, diluted, or if it has been tampered with in order to mask drug metabolites. Today’s lab tests measure specific gravity, pH, creatinine levels, and temperature, determining a “positive” or “negative” result and attempts at cheating a drug test are more detectable than ever.
Employers Depend on Accurate Results
Many employers, such as the United States Department of Transportation (DOT) and agencies and contractors that must abide by its rules, take a “split specimen.” At the time of collection, the sample is separated into two vials. The first is tested immediately according to regular procedures described above. The second belongs to the sample donor and is available for secondary testing if they don’t agree with the initial test results.
