![]() As such, our scientific experts continue to monitor new generations of products and adjust accordingly. Unfortunately, the cheating industry continues to develop products and systems that may be undetectable in standard urine drug tests. These labs are inspected on regular intervals throughout the year as well as participate in proficiency testing (PT) programs, which include challenges to the laboratory’s ability to perform routine specimen validity testing accurately. It’s important to work with a drug testing provider that performs specimen validity testing in a certified laboratory.All urine drug test specimens coming into Quest Diagnostics facilities include specimen validity testing as part of the drug testing process. Yes, Quest can detect some synthetic urine using specimen validity testing, a screening that determines if a specimen is human urine. Can synthetic urine be detected in a drug test? However, manufacturers of synthetic urine have responded by adding these additional constituents to their products in an effort to defeat these additional SVT tests. Over time, additional chemical tests of specimen validity have been proposed and, in limited cases, used by drug testing laboratories. Synthetic urine is essentially water that has been fortified with various constituents such as creatinine, salts, and yellow coloring in an effort to make a specimen appear to be normal human urine and pass standard tests of specimen validity. One method by which donors attempt to undermine the integrity of the drug testing process is by substituting their urine with synthetic urine. We first patented our screening technology for oxidizing adulterants in 2000 and testified before Congress in 2005 on “Products that Claim to Prevent Detection of Certain Substances by Drug Testing Programs.” Today, we remain one of the few SAMHSA-certified laboratories capable of performing oxidizing adulterant identification. ![]() ![]() We continue to be pioneers in specimen validity testing (SVT) – a screening to help ensure the integrity of the urine specimen and drug test. At Quest Diagnostics, we take the issue of subversion of the drug testing process very seriously.
