Smartphone-Breathalyzer study

A University of Pennsylvania study comparing the accuracy of blood alcohol levels measured by commercial smartphone Breathalyzers vs. police-grade units is currently enrolling participants.

The research is funded by the Penn Injury Science Center and led by M. Kit Delgado, MD, an assistant professor of emergency medicine who is affiliated with the center, which provided the following information.

About the study

  • Individuals aged 21 and older without chronic medical problems or a history of alcohol use disorder are eligible to participate.  Screening is over the phone with a research coordinator.
  • The study is conducted in a clinical research lab at the Hospital of the University of Pennsylvania.
  • Participants are given a weight-based dose of alcohol and then serial breath alcohol measurements are taken using commercially available smartphone-paired Breathalyzers and a police grade Breathalyzer.  A blood alcohol level is also drawn for comparison.
  • Participants are compensated for their time.
