Smocha, I was told to also take to the USDA a "rabies certificate," which is not the same thing as the titre page, but one from my own vet showing his microchip number plus the date of his rabies shot that preceeded the blood draw/titre, and the type of vaccine, along with my own vet's signature and clinic stamp. This is to confirm to the USDA vet the same info that my own vet filled out on the 998 in the appropriate sections. I think the USDA want this brought along too just so that they can compare and verify the information on all three pieces of paperwork -- the FAVN titre result from Kansas, the 998 information filled out by your vet, and this other set of rabies vacc details also provided by your vet.
At least, that's the three pieces of paper a transport agent told me my local USDA office would want to inspect before endorsing -- possibly your USDA will want to see all three too? I can't say for sure, I only know those were what I had to bring to them.
I can e-mail you the scan of this other vet-isssued "rabies certificate" if you need me to?
