Intoxilyzer 5000 and blood-alcohol results from drivers arrested for operating a motor vehicle while intoxicated and for related offenses were compared during a two-year period. Three hundred and ninety-five pairs of results were studied. The breath- and blood-alcohol specimens in this study were collected within 1 h of each other. The mean blood-alcohol concentration obtained was 0.180 g/dL, with a range from zero to 0.338 g/dL. By comparison, the mean Intoxilyzer 5000 result was 0.16 g/210 L with a range from zero to 0.32 g/210 L. Compared with the blood-alcohol result, Intoxilyzer 5000 results were lower by more than 0.01 g/210 L 67% of the time, within 0.01 g/210 L 31% of the time, and higher by more than 0.01 g/210 L 2% of the time.
在两年时间里，对因醉酒驾驶机动车及相关违法行为被捕的司机的Intoxilyzer 5000检测结果和血液酒精检测结果进行了比较。研究了395对结果。本研究中的呼气酒精和血液酒精样本是在彼此1小时内采集的。测得的平均血液酒精浓度为0.180 g/dL，范围从零到0.338 g/dL。相比之下，Intoxilyzer 5000的平均检测结果为0.16 g/210 L，范围从零到0.32 g/210 L。与血液酒精检测结果相比，Intoxilyzer 5000检测结果在67%的时间里比血液酒精结果低超过0.01 g/210 L，在31%的时间里与血液酒精结果相差在0.01 g/210 L以内，在2%的时间里比血液酒精结果高超过0.01 g/210 L。
