The IFA tests weather the virus is replicating in the bone marrow. You can have
a positive SNAP & a negative IFA. This does NOT mean the cat is negative. It
just means the virus is not replicating in the bone marrow.
Any test can be done wrong & labs can mix up donors with specimins. It happens
with humans, it can certainly happen in our pets.

The IFA is not testing the bone marrow, though....that would be yet another
test.

It is possible the SNAP tests were positive & an IFA was negative because
the virus had not progressed to the bone marrow. I also wonder if the SNAP
tests that were positive were done on the new 3way tests. Our shelter
stopped using them because they were not dependable.
