This work reports on the statistical evaluation of a field trial in which the breath alcohol concentration, as measured by the "alcytron", was compared with the blood alcohol concentration of the same donors. The infra-red testing equipment "alcytron" was operated by police officers, who determined the breath alcohol concentration of 132 test subjects on the police beat. Both the breath- and also the blood-alcohol determination were carried out in the elimination phase, as shown in the statistical evaluation. In the computer program allowance was made for a number of parameters such as sickness, physique and similar factors, which could possibly affect the breath alcohol concentration, although no statistically proven influence could be established. The regression analysis produced a very good agreement between breath- and blood-alcohol concentrations with high correlation coefficients. For 47 test subjects there was complete agreement, for 9 divergencies greater than or equal to 0.2 per thousand were found. For a triple standard deviation the estimated error of blood- to breath-alcohol concentration was determined at 0.3 per thousand. (TRRL)
