I don't know if you would call it a false negative. It is possible for a cat
to be so recently exposed to the FeLV virus that it will not show up on the
test. That's why many recommend retesting a few weeks later.

Are these normally just inaccurate as far as false positives go? Are there ever
any false negatives?
