In vivo repeatability and reproducibility of the quantitative light-induced fluorescence (QLF) method were tested with respect to three variables: lesion area, and average and maximum changes in lesion fluorescence. To test the image-capturing stages, three analysts each captured images of 15 incipient smooth surface lesions in vivo, and the images were analysed by one of the analysts. To test the analytical stage of the method, three analysts analysed the images of 15 in vivo incipient smooth surface lesions. For the image-capturing stage, inter-examiner reliability showed an intra-class correlation coefficient (r) between 0.95 and 0.98. For the analytical stage, intra-examiner reliability for all three analysts showed a value of r between 0.93 and 0.99. Inter-examiner reliability showed a value of r between 0.95 and 0.99. It was concluded that the in vivo repeatability and reproducibility of the QLF method are excellent.
针对病变面积、病变荧光的平均变化和最大变化这三个变量，对定量光诱导荧光（QLF）方法的体内可重复性和再现性进行了测试。为测试图像采集阶段，三名分析人员分别在体内采集了15个初期光滑表面病变的图像，然后由其中一名分析人员对这些图像进行分析。为测试该方法的分析阶段，三名分析人员对15个体内初期光滑表面病变的图像进行了分析。对于图像采集阶段，检查者间可靠性显示组内相关系数（r）在0.95至0.98之间。对于分析阶段，所有三名分析人员的检查者内可靠性显示r值在0.93至0.99之间。检查者间可靠性显示r值在0.95至0.99之间。得出的结论是，QLF方法的体内可重复性和再现性极佳。
