title: Interpreting feline leukemia test results.
abstract: Routine prevaccinal screening for FeLV has inherent statistical limitations owing to the magnification of false-positive test errors by the low prevalence of FeLV viremia in the general cat population. Positive ELISA test results obtained in a screening program should be interpreted with caution, because a high proportion--approximately 72%--of such are likely to be false-positive results. On the other hand, routine screening is an excellent method for ruling out FeLV viremia, because a false-negative result is likely to be obtained in only 1/1,000 tests.
