My vet charged me $153 for the rabies titer in early 2012. I wanted it done prior to the three-year mandatory vaccination coming up that May. They sent it to KSU from Albany, NY and gave me some babble about it had to go through IDEXX or something and that's why it cost so much - plus KSU was the ONLY place performing this titer. I was not aware of Hemopet at that time so I had no argument.
The titer came back with good ratios, however, my vet said of course I knew that this did not prevent my dog from being required to get his vaccination and that this did not warrant a medical waiver. Oh, of course, go right ahead - why should this result that nobody else has ever asked you for outside of traveling make you think that there's an issue with vaccinating immunized dogs?????
