Those are the same tests. The definitive test is the IFA (has to be sent to a lab). Recommended testing protocol is if the "snap" and IFA are different, test again in 120 days. Unfortunately for most rescues and shelters they don't have a place for keeping possibly positive cats for an additional 120 days. If the "snap" test was done using the new triple test (FIV, FeLV and heartworm) have it done again using the FeLV test only, if you can find a vet who has them. There have been many false positives reported with the triple test.

I know I have read there is a chance of a false positive with the snap test. I was wondering if the same with the Elisa test? Thank you.
