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.

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 the other laboratory tests used to detect pironoma.
C In treating pironoma patients, it is essential to begin treatment as early as 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 negative results

Why is the Answer E , I would go with B, Makes Most Sense

Thanks

The best option is to reduce both FN and FP (False Negative) and (False Positive). Since you cannot reduce FN as per E. Best option is to reduce FP. Therefore E.
