Quest Diagnostics Drug Testing Index webinar

Our scientists discuss the latest workplace drug testing data

The Quest Diagnostics Drug Testing Index™ 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. Topics include:

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

Two Quest Diagnostics experts, R. H. Barry Sample, PhD, senior director of science & technology, and Kimberly Samano, PhD, scientific director, discuss the latest data and trends.
