What is Adulteration?
Adulteration is the tampering of a urine specimen with the intention of altering the test results, rendering a positive reading into a negative one. Users of illicit drugs have attempted to defeat drug test by adding adulterants to the sample after collection as a way to invalidate the testing procedures. The use of adulterants can cause false negative results in drug test by either interfering with the screening test or converting the drugs present in the urine to other compounds. In addition, some donors try to substitute their specimen with another liquid and others may dilute their specimen by consuming excessive amounts of fluid or by adding water/other liquids to their specimen after collection.
Adulteration is the tampering of a urine specimen with the intention of altering the test results. The use of adulterants can cause false negative results in drug tests by either interfering with the screening test and/or destroying the drugs present in the urine. Dilution may also be employed in an attempt to produce false negative drug test results. One of the best ways to test for adulteration or dilution is to determine certain urinary characteristics such as creatinine, pH, and specific gravity and to detect the presence of glutaraldehyde, nitrite and oxidants /pyridinium chlorochromate (PCC) in urine.

Creatinine and specific gravity are two ways to check for dilution and flushing, which are the most common mechanisms used in an attempt to circu
TOP Adulteration is the tampering of a specimen in an attempt to pass a drug screen. There are several household products that are used as well as over the counter products that are either ingested or added to the specimen. Access to information on the Internet has increased the number of attempted adulterated specimens. Any specimen that has been adultered is considered a positive at our facility.
