FYI - did someone already post this? Seems familiar.
<http://www.facebook.com/profile.php?id=654216039> Sam Thomas >From A Feral Cat Chat List..... I just learned some very interesting information about FELV. ??? had three cats test positive for it, when they knew that it was very unlikely ( neither the mother nor any of the other kittens in the litter tested positive, after repeated tests and they had the mother with them for a while before birth. One of the vet volunteers followed up. She had blood drawn at Caring Hands Vet and sent to Auburn University College of Veterinary medicine Pathology Diagnostic Services , which does some different tests, at about $30 cost. Auburn University College of Veterinary Medicine Pathobiology Diagnostic services says that the Idexx SNAP test can cause a positive result because some cats have a reaction to the cat serum in the test. They did two other tests on all three cats using a blood test called IFA as well as by another ELISA test called Symbiotics Viracheck. All three cats tested negative on both tests. And they concluded that they had reacted to the serum used in the Idexx SNAP test!! Also we should get the word out that the Idexx tests can cause false positives> The number of the Auburn University facility is 334-844-2690
