Adulteration Testing

Adulteration testing is instrumental for detecting occurrences of commercially available products and dishonest methods often used to tamper with urine drug test results.

Drug users commonly dilute urine samples or introduce such additives as household cleaning agents, vinegar, soft drinks, eyedrops, etc., to interfere with drugs-of-abuse screening.

Employee Screening Management can test the integrity of a urine specimen with ProScreen™ Drugs of Abuse Card, which contains multiple assays for indicating suspected adulteration or substitution.

The Adulterant Interpretation Key (as shown on this page) provides a foundation for dependable, accurate results interpretation prior to drug screenings.

Contact Employee Screening Management at info@pre-screen.com or 1.888.371.4615 for additional information.
