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

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

Margo, I rescue too, and I've reached the same conclusion as you have. 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 do I do

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

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
