Data regarding this self-test device's ability to accurately classify an individual as having 0.10% (or higher) Breath Alcohol Concentration level are reported. This level was selected because it is the legal per se limit for operating a motor vehicle in many states. The results indicate that, at optimal environmental test temperatures (around 75 deg F), a large proportion of individuals with BACs at or above this level would be inaccurately classified as below 0.10%. Also, at more moderate test temperatures (around 60 deg F), the extent of inaccurate classifications and the degree of underestimation of the actual BAC level increases substantially. /Abstract from report summary page/129
