Blew my mind, too - also my vet's and the cat's previous vet's in NJ!
I think he was given the IFA much too soon after the ELISA - that could be
it - but who knows....I'm just grateful that they're both negative...

Wow, Natalie, this is a great test result but it blows my mind. How does 
that happen?

The strange thing is that one of our previously tested FeLV cats had the
ELISA (positive), then the IFA (positive)before I got him (maybe it was done
too soon after the ELISA?).  Then I had both cats tested with IFA - both
negative!!!!

The IFA tests to see if the virus has gotten into the bone marrow & is not
reversible. A negative IFA does NOT mean the cat is not FeLV positive.

If I may...
The IFA is more expensive, but results are more reliable. My vest advised,
"If the snap (vet's office) test is positive, you need to do IFA. If the
snap is negative, you probably don't need IFA."
Good for you for trying to be as sure as you can be. And thank you for
helping our furry friends!
Buena suerte!

I think the standard snap test which just looks for FIV & FeLV is probably
more reliable than the triple test. Not sure though.

The IFA that Natalie mentioned looks to see if the virus has gotten into the
white blood cells, and if so then the cat will not get rid of the virus and
you can say for sure he's FeLV positive. But if it is just in his
bloodstream, which is what the snap test checks, then the cat still has a
chance of getting rid of the virus. Someone please correct me if I am
wrong.

So you have a couple of options -

You can do another snap test to make sure the first one was right, or you
can go ahead and do the IFA test.

If you do another snap test and it comes out negative then you don't need to
do anything else. But if the second snap test is positive then you'll need
to do more testing.

If you skip the snap test and go ahead and do an IFA test right now to see
if the virus is in his white blood cells, and it's positive then you know
for sure that he will not be able to get rid of the virus. However if it is
negative, then you will need to do another test in a few months to see if
the virus is present then because it could be in his blood stream now but
not go to his white blood cells for another few months.

Basically, you need two tests that match.

Hi!

Thanks for your answer.... Yes, I can retest them... my doubt is, which test
should I use? Which one is the most reliable?


Thanks!
Ana
