[Felvtalk] Light positive reading

[Amy]

The rescue I'm part of had 4 kittens that all tested positive for leukemia.  We held them all and retested later and found one negative, some weak positives and a strong positive.  We retested again later, all 4 negative.   We spoke with somebody at the ASPCA and they said if it had been one kitten, they may have thought test error.  Since all 4 converted and still remain negative, it appears the weak positive showed they were clearing the virus from their system.  We got very lucky!

Many years ago (early 80's I think), I had a cat that supposedly showed 
a faint positive.  The vet thought maybe it was a mistake, and a later 
test turned up negative.  I have heard that it is always a mistake, and 
I have also heard the theory that a cat is fighting off the infection. 
Anybody want to contact a manufacturer?
