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 in urine.
These adulterants are often oxidative in nature - hydrogen peroxide and bleach have been used, sometimes with pH-adjusting substances like vinegar or sodium bicarbonate. These can be detected by drug testing labs or you can buy bottles of AD test strips that can be purchased as an accessory for drug testing to assure urine specimen validity.
Intect 7 is designed to detect adulterants in a urine specimen. By detecting the levels of creatinine, the presence of nitrite, glutaraldehyde, pH, specific gravity, and of oxidants, including bleach and pyridinium chlorochromate, Intect 7 determines the integrity of the donor's sample. Intect 7 is the most effective screen for sample validity testing on the market. Popular adulterants that Intect 7 detects:
- Urine Luck 6.3 and 6.4
- Clear Choice
- Instant additive
- Lucky Lab LL418
- Liquid hand soap
- Detoxify Cleansers
