Abstract
In an experiment, multiple reagent test strips from 90 urine samples were examined twice: observed visually by one of two persons and analyzed by spectrophotometry. Interobserver and intra-observer agreement were calculated and expressed as Cohen's K. Interobserver and intra-observer agreement were moderate to good, but lower than one might expect. Enhancing discoloration of the test pads could improve reproducibility.
摘要
在一项实验中，对 90 个尿液样本的多个试剂测试条进行了两次检查：由两个人中的一个进行目测检查，另一个人用分光光度法进行分析。计算了观察者间和观察者内的一致性，并表示为 Cohen 的 K。观察者间和观察者内的一致性为中度至良好，但低于预期。增强测试垫的变色可以提高重现性。
