Adulteration Tests

When a drug test has been administered, the biggest concern is if the urine sample has been adulterated. Drug screens test for the presence of drugs in the donor's urine but not the integrity or validity of the urine sample. Commercial adulterants are sold over the internet, in magazines, as well as in head shops with the sole purpose of defeating drug of abuse screens. According to published data, over 8% of all negative drug tests are false negatives. However, the actual number is unknown because routine laboratory tests do not pick up all possible adulteration products. It is also known that the newest generation of adulterants is able to disintegrate and become undetectable after its effects on the positive sample.

To combat against urine adulteration, sample validity tests such as Intect^® 7, ToxCup^®, Monitect^®, and Quicktox^® are designed with built-in adulterant pads to confirm the integrity of the urine sample. Adulterants that can be detected include: Creatinine, Nitrite, pH and Oxidants.
