87. 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.
