Measurements of blood alcohol concentration (BAC) were made on patients who presented to an accident and emergency department with acute alcohol intoxication. A correlation of r = 0.418 was noted to exist between BAC as measured by sampling saliva and blood. Blood alcohol concentrations as measured by salivary reagent strip (ALCO-SCREEN, Chem Elec.) were significantly lower (p less than 0.0001) than those determined by gas chromatography of serum. Although such reagent strips offer a rapid measurement of BAC, it is concluded that they are unreliable for the quantitative measurement of BAC in accident and emergency departments.
对因急性酒精中毒到急症室就诊的患者进行了血液酒精浓度（BAC）测量。通过采集唾液和血液测量的BAC之间存在r = 0.418的相关性。唾液试剂条（ALCO-SCREEN，Chem Elec.）测量的血液酒精浓度明显低于血清气相色谱法测定的浓度（p小于0.0001）。尽管这种试剂条可快速测量BAC，但得出的结论是，它们在急症室对BAC进行定量测量时不可靠。
