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 –
see below - for a total of up to 506 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
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, but information pertaining to what
the individual consumed, how much the individual
consumed, and exactly when the individual
consumed each 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.
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.

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" --
