There's a new DNA test for FIV, which is preferred over the old western blot now because it can tell a true positive from a vaccinated positive.
Yes, the IFA is the usual confirmatory test for FELV though. Here's all the info on the FIV testing (your vet may not be aware of it yet, as it is VERY new, so print this out and take it with you): http://www.vetmed.ucdavis.edu/ccah/Homesite%20Images/Diagnostic%20PCR%20Price%20Schedule.doc (you have to scroll down quite some way to the section titled FIV DNA Testing Information.)
