Quest Diagnostics Drug Testing Index webinar

Our scientists discuss the latest workplace drug testing data

The Quest Diagnostics Drug Testing Index™ (DTI) reveals insights into patterns of drug use among the American workforce. Published annually since 1988, the report examines test results according to three categories of workers: federally-mandated, safety-sensitive workers; the general workforce; and the combined U.S. workforce. A few of our topics include:

  • Overall positivity for the combined U.S. workforce
  • Positivity by testing reason and drug category
  • Urine, oral fluid, and hair positivity

Join R. H. Barry Sample, PhD, senior director of science & technology at Quest Diagnostics, and Kimberly Samano, PhD, scientific director at Quest Diagnostics, as they discuss the latest DTI data and trends.
