87. In test 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.
Which of the following, if true, gives the most support to the recommendation above?
(A) The accepted treatment for pironoma does not have damaging side effects.
(B) The laboratory test that has the lowest proportion of false positive results causes the same minor side effects as do other laboratory tests used to detect pironoma.
(C) In treating pironoma patients, it is essential to begin treatment as early as do possible, since even a week of delay can result in loss of life.
(D) The proportion of inconclusive test results is equal for all laboratory tests used to detect pironoma.
(E) All laboratory tests to detect pironoma have the same proportion of false negeative results.
fail prositive,没有病说有 fail negetive,有说没有
要最accurate,就是宁可错杀3000不可放过一个,当然要用lowerst negetive。
为什么conclusion说positive?? e为什么加强了 结论呢??
我知道我的思路很好笑,请解惑
