  Testimonials
"I love this program!  It allows me to communicate with defense attorneys and prosecutors with numbers and graphics in my hand!  This goes a long way toward getting plea agreements and cases settled without a trial" -- Debra S., Forensic Toxicologist, Texas, USA.

"BAC Tracker software has caused me to change the way in which I report alcohol use in medico-legal reports" -- Dr. Edward Ogden, Victoria, Australia.

"Expert witnesses involved in litigation arising from alcohol consumption will find BAC Tracker to be very useful" -- Michael D. Corbett, Ph.D, Omaha, Nebraska, USA.

"In conjunction with our continuing research, BAC Tracker has provided additional corroboration of our internal methods in the assessment of DUI cases" -- Analytical Research Laboratories, Oklahoma City, Oklahoma, USA.

"BAC Tracker allows me to evaluate potential new cases, better understand my client's case, prepare for trial and when possible, use in trial" -- Patrick Barone, Barone Defense Firm, Birmingham, Michigan, USA.

About BAC Tracker Software

BAC Tracker software is a computer analysis program that allows for a more comprehensive estimation of blood alcohol concentration (BAC) using every major published formulae accounting for volume distribution. BAC Tracker employs the latest scientific data for more accurate and balanced results in the court room when estimating BAC. BAC Tracker combines professional software development with the expertise and experience of seasoned individuals having backgrounds in forensic toxicology, medicine, and law.

Three separate types of extrapolation reports ¨C see below - for a total of up to 508 separate reports can be generated within seconds using BAC Tracker which are derived from every major published formulae accounting for volume distribution and calculated against every combination of absorption and elimination rates. Data input requires only the individual¡¯s gender, age, weight, height, and either known drink consumption information or a known BAC/BrAC reading. The software will automatically run the data against six different volume distribution formulae (and any combination thereof) which take into account the individual¡¯s gender, age, weight, height, body mass index, percent body fat, water content in blood, water content in fat-free body mass, total body water, multiple non-linear rates of absorption, and multiple separate rates of elimination. Further data entry can be applied to both the rate of absorption to account for factors affecting gastric motility and the rate of elimination by applying broad or narrow ranges to account for inter- and intra-individual variations in the human population. The result is the most comprehensive estimation of blood alcohol concentration while accounting for every known source of uncertainty.
 

Anterograde Alcohol Extrapolation Report

This report provides a comprehensive, multi-point curve extrapolation of the entire drinking scenario when a no analytically determined known BAC is available, but information pertaining to what the individual consumed and approximate times of consumption are known. This type of report may generate up to 252 different reports using any combination of the six volume distribution formulae calculated with various combinations of absorption and elimination rates chosen by the user.
 

Retrograde Alcohol Extrapolation Report

Two different types of Retrograde Alcohol Extrapolation Reports (Type I or Type II) can be generated depending on whether relevant begin and end times of alcohol consumption are known.

TYPE I RETROGRADE ALCOHOL EXTRAPOLATION REPORT: This report provides a comprehensive, multi-point curve extrapolation of the entire drinking scenario when an analytically determined known BAC is available as well as approximate times of alcohol consumption (time of first drink and time of last drink), but information pertaining to what the individual consumed, how much the individual consumed, and exactly when the individual consumed each individual drink are unknown. This type of report may generate up to 252 different reports using any combination of the six volume distribution formulae calculated with various combinations of absorption and elimination rates chosen by the user.

TYPE II RETROGRADE ALCOHOL EXTRAPOLATION REPORT: This report provides a multi-point extrapolation of the blood alcohol concentration when an analytically determined known BAC is available, but information pertaining to what the individual consumed, how much the individual consumed, and exactly when the individual consumed the alcohol are unknown. This type of report assumes alcohol absorption is complete and estimates the BAC by calculating the amount of alcohol metabolized between the Time of Interest and the Time of the Known BAC taking into account the uncertainty associated with alcohol elimination. Additionally, the software will take into account the uncertainty associated with the known BAC from QA/QC data to ensure all sources of uncertainty are accounted for in the extrapolation.
 

Alcohol Quantification Report

This report provides a comprehensive extrapolation of the amount of alcohol consumed by an individual in order to reach a particular BAC after a specified time lapse since the first drink of alcohol. This report quantifies the amount of alcohol (displayed in grams and volume of 100% alcohol by volume as well as the number of user defined ¡°Standard Drinks¡±) according to each of the six different volume distribution formulae and calculated using various rates of elimination chosen by the user thereby taking into account the uncertainty associated with the volume distribution and elimination. Additionally, the software will take into account the uncertainty associated with the known BAC from QA/QC data to ensure all sources of uncertainty are accounted for in the extrapolation.
