[Felvtalk] Tests

[Lee Evans]

One of my rescues, "Taco", tested positive for FIV and FeLv on the combo test.  I tested Taco with the IFA test.  He came up negative for FeLv.  I intend to do one more test.  Is there a third test that I can do that would reassure me that he is really FeLv negative (or positive)?  He has been with me for two months since the second test.  I can't put him in my FIV+ group and I can't put him in my regular cat group.  He is one lonely neutered boy right now, in a room by himself.  I was told by my vet that he could have the PCR test done.  I once did this test on Moses, another rescue who came up negative on the FIV test but positive for FeLv on the ELISA.  When tested with the IFA and the PCR tests, he was negative.  I then had the ELISA done again and it too was negative. I added him to my regular cats.  He's still with them and no problems so far after 4 years.
 
So, can anyone here recommend a third test for Taco that would allow him to go into my FIV+ group?
