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?

• AThe accepted treatment for pironoma does not have damaging side effects  
• BThe 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  
• CIn 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  
• DThe proportion of inconclusive test results is equal for all laboratory tests used to detect pironoma  
• EAll laboratory tests to detect pironoma have the same proportion of false negative results
