Vaccine Titers
Blood tests measuring disease-specific antibody levels to assess whether revaccination is necessary.
Key Facts
- Only valid for canine distemper, adenovirus, parvovirus, and feline panleukopenia
- Cannot be used for rabies (legally mandated vaccination schedule)
- High titer suggests protection but does not guarantee 100%
- Low titer does not necessarily mean unprotected (immune cells persist)
- Useful for pets with history of severe vaccine reactions
- Becoming more affordable and accessible
- Snapshot of antibody levels at one point in time only
