Comparison of spot tests with AdultaCheck 6 and Intect 7 urine test strips for detecting the presence of adulterants in urine specimens

Is this urine really negative? A systematic review of tampering methods in urine drug screening and testing

“…Additionally, the Intect 7 detected the presence of Stealth (detected in bleach and PCC panels), as well as vinegar and ammonia (detected in the pH panel). In a more recent study of the Intect 7 and AdultaCheck 6, Dasgupta, Chughtai, Hannah, Davis, and Wells, (2004) reached a similar conclusion, noting the advantage of Intect 7 in detecting specific gravity and the presence of bleach.…”

Drugs of Abuse Testing

“…are available for detecting these adulterants [13]. These products usually contain strong oxidizing agents such as potassium nitrite, pyridinium chlorochromate, glutaraldehyde, and Stealth (hydrogen peroxide and peroxidase).…”

Determining the effects of adulterants on drug detection via enzyme‐linked immunosorbent assay and adulterant tests strips

“…In some workplace settings, it is not always feasible to have the individual ingest a digestive marker to ensure that the urine sample collected was provided by them, in an effort to mitigate the potential for adulteration. [8][9][10] Immunoassay tests are ideal for screening drugs due to the high specificity of the antibodies to a variety of analytes. These adulterants may produce a false negative on immunoassay-based drug pre-screenings.…”

“…15 Studies suggest that the hydrophobic interior of the benzalkonium chloride micelles in the eye drop solution will be partitioned by the THC metabolites causing a reduction of available metabolites for antigen-antibody reactions. 9 AdultaCheck® 6 (AC6) and Intect™ 7 (In7) are 2 commercially available tests that have been evaluated by other researchers. To detect the presence of adulterants in urine samples many laboratories will use adulterant test strips.…”
