Celebrating 25 Years of the Drug Testing Index™

by Nicole Jupe on October 1, 2013

DTI 25th Anniversary sealQuest Diagnostics proudly celebrates the 25th anniversary of the Drug Testing Index (DTI). During the past 25 years, we have seen the engagement of both public and private sectors focusing on the identification of drug users in the interest of public and workplace safety. Insights from our DTI reports have provided workplace drug use trends while our testing products and solutions have helped to keep drug users out of the workforce.

In examining the data, Dr. Barry Sample, Director of Science and Technology at Quest Diagnostics, noted the following:

  • Employers who drug test have seen their drug test positivity rates decline over time.
  • The popularity of random testing has increased in non-federally mandated drug testing programs.
  • DTI data mirrors U.S. population trend data in the areas of amphetamines, cocaine and prescription opiates use.
  • Oral fluid testing technology provides drug detection at comparable levels to urine drug testing.
  • As expected, lower drug testing cutoffs detect more drug use.
  • Specimen validity testing data shows that the rate of specimens failing validity testing – adulterated, substituted, and invalid – has remained consistent over time.

We are excited to share this 25th anniversary timeline which tracks the evolution of our industry, notes milestones in drug testing and illustrates our steadfast commitment towards helping to keep workplaces safe and drug-free. Stay tuned over the next five weeks as we take a deeper dive into a series of five-year periods in time, and as we examine the societal impacts of drug use and drug testing.

We believe in the benefits that drug testing delivers. We also believe in the value and insights that the Drug Testing Index provides.

25 years of the Drug Testing Index – just one of the many ways we show we’re there when you need us.
