In tests for pironoma, a serious disease, a false positive result indicates that people have pironoma when, in fact, they do not; a false negative result indicates that people do not have pironoma when, in fact, they do. To detect pironoma most accurately, physicians should use the laboratory test that has the lowest proportion of false positive results.

这个lowest proportion of false positive results到底是指什么呢？我明白肯定是要用false positive的结果，但是这个lowest proportion把我彻底弄混了，到底这个里比例是指的什么？我想来想去都没理出个所以然，晕了，麻烦大家给我好好讲讲

测试pironoma有两种结果：false positive 和 false negative

保证测量的准确度，要求最小的false positive的比例，那只有保持false

negative不变，及排除他因。

这个lowest proportion of false positive results到底是指什么呢？

我觉得是false positive results占所有两种测量结果的比例最小。
