Comparison of spectroscopically measured finger and forearm tissue ethanol concentration to blood and breath ethanol measurements.
Previous works investigated a spectroscopic technique that offered a promising alternative to blood and breath assays for determining in vivo alcohol concentration. Although these prior works measured the dorsal forearm, we report the results of a 26-subject clinical study designed to evaluate the spectroscopic technique at a finger measurement site through comparison to contemporaneous forearm...
متن کاملMedicolegal Alcohol Determination - Blood- or Breath-Alcohol Concentration?
Measuring the concentration of alcohol in body fluids represents a large part of the workload at forensic science and toxicology laboratories. In traffic-law enforcement, breath-alcohol testing is used worldwide for roadside screening and for evidential purposes. Many jurisdictions have adopted per se laws which make it a crime to drive with a blood- or breath-alcohol concentration above a pres...
متن کاملBreath Alcohol Concentration and Breath Temperature
Breath alcohol concentration, breath temperature, and body temperature are used to extrapolate the breath alcohol concentration to the concentration of alcohol in the deep lung air, which is in equilibrium with the pulmonary blood. Introduction The variability that is seen in the breath alcohol test (note: “alcohol” means ethyl alcohol) has always been more or less ignored as inevitable “biolog...
متن کاملDeconvolving an estimate of breath measured blood alcohol concentration from biosensor collected transdermal ethanol data
Biosensor measurement of transdermal alcohol oncentration in perspiration exhibits significant variance from subject to subject and device to device. Short duration data collected in a controlled clinical setting is used to calibrate a forward model for ethanol transport from the blood to the sensor. The calibrated model is then used to invert transdermal signals collected in the field (short o...
متن کاملMedicolegal alcohol determination: variability of the blood- to breath-alcohol ratio and its effect on reported breath-alcohol concentrations.
There is substantial agreement among scientists that the variability of a person's blood- to breath-alcohol ratio contributes significantly to the experimental error in results from breath-alcohol analysis. Some have argued that the need to correct for this source of error can be eliminated by reporting breath test results in units of breath-alcohol concentration rather than blood-alcohol conce...
