In tests for Feline Leukemia Virus (FeLV), a serious disease of domestic cats, a false positive result indicates that a cat has FeLV, when in fact, it does not; a false negative result indicates that a cat does not have FeLV when, in fact, it does. To detect FeLV most accurately, veterinarians should use the laboratory test that has the lowest proportion of false negative results.
Which of the following, if true, gives the most support to the recommendation above?
A A certain proportion of results are inconclusive no matter which laboratory test is used.
B There is no known cure for FeLV, although some chemotherapeutic agents may produce a temporary remission and some antiviral agents may reduce the amount of virus present in infected cats.
C Cats do not readily submit to having their blood drawn for a test.
D Upon receiving a positive test result, veterinarians often submit a second sample to be retested for confirmation.
E All laboratory tests to detect FeLV have the same rate of false positive results.
OA E
