Validation Study and Report

Reference List

BAC-Tracker has been evaluated and validated in controlled drinking studies to be effective in providing an accurate estimation within a 0.01g% deviation of the observed BrAC of individuals in the fasting state.

Study volunteers were orally administered various amounts of alcohol by law enforcement officers according to standard procedures. Their BrAC was recorded at certain times throughout the study using an Intoxilyzer® 5000. BAC-Tracker was able to generate alcohol extrapolation reports that accurately estimated the BrAC for each study volunteer.
