I don't have anything other than anecdotal experience, but we ran IFAs on
my four who were 14 weeks old and all were positive.

is the IFA test valid and reliable on a 12 week old kitten? If not do you
have links? I'm thinking I've heard it isn't, but can't find anything.

Hi,
Thanks for the replies to my initial question. Lots of good insight regarding
testing.
I didn't realize about the PCR's showing regressive infection, thanks Lance.
Does that mean
same as latent? I just have one positive cat, so the test expense is something
I would spring for if
it might
when they are cats.
Spay and Neuter your cats and dogs and your weird relatives and nasty neighbors
too!

Like others who have replied, I have worked with cat rescues and have
personal experiences w/ FeLV. I trust ELISA and IFA results if done
properly. However, I wouldn't run a PCR test. I feel this test is
EXTREMELY sensitive and any sort of mishandling will result in an
untrustworthy result. One
If I understood the AAFP retrovirus guidelines paper, PCR tests are the only
test that will show regressive infection. Theoretically, regressive infections
rarely if ever surface. In other words, a true negative on ELISA/IFA should not
"go positive" later on down the line.
Testing, like vaccina
n-releaseables from here. They are quite numerous.
But the current crew is safe. They stay.

This testing and retesting doesn't let us know what is really going on.
It is so discouraging, as well as extremely expensive when you have a
lot of rescued cats. Believe me I'd like to stop rescuing too, but what

Thanks Katherine.
I think I have heard that too about PCR accuracy.

Maybe I'll learn more (or someone else will) and change my mind.

Shelley,
One of my vets (I'm in the US) did a PCR test, but another always does IFA
(for kittens who test positive on snap ELISA) and that seems to be more
common. I asked my vet why she chose the PCR test and she said it was more
accurate. PCR results seemed to take longer than the IFA but I've a
Hi,
I want to bring Leo back in to get the IFA test. I was reading about the
company that developed
the IFA test, the National Veterinary Lab. Are they the company that most
folks use or can
my vet send to any lab, like Antech, etc. Is one lab considered more accurate
than another?

Remember I wrote the other day about our two FeLV+ boy cats that I had
retested by IFA method last week, and were both negative?
I just found out that Mr. Tux, whom I got from a rescuer in NJ, had the
ELISA 2 yrs ago and IFA 2 months later by another rescuer - BOTH were
positive! My Eliot Spitty ha
this is what is stated by a lot of people, but i really need to see some

not stated in the definitive way that i see it used.
