Hi everyone-- I think I saw the question on here as to why retesting needed to be done for allergies, although I apologize that I don't recall as I type this who asked it. My (non-scientific!) answer is that I don't believe retesting is common at all. In fact, the reason we 'went against the grain' and retested three times was:
1. my vet first tried skin testing and it gave us no results
2. then we tried blood testing and made appropriate diet switches based on the results
3. all was fine, until about a year later when Holly began getting severe hot-spot flare-ups and constantly scratching, etc. We went in for a retest, wondering if she'd developed an allergy to anything in her food that she hadn't been allergic to previously. Our vet said this was possible, especially given her age.
Despite all that, given the widely varying results, I think we're going to give the elimination diet a try and see how that goes. Thanks for the advice everyone.
