TITER TESTING
Veterinary titer tests are blood tests that measure a peti’s antibody levels to determine immunity against diseases like distemper, parvovirus and adenovirus. They help avoid over-vaccination, tailor vaccination schedules, and identify if a previously vaccinated pet still has protection. They are valuable for pets with vaccine sensitivities, chronic diseases, or in cases of unknown vaccination history.
Key Information for Pet Owners
What They Measure: Titers identify the concentration of antibodies, indicating if a pet has likely been exposed to a disease or vaccine and has built immunity.
Core Vaccines: Generally used for core diseases (distemper, parvo, adenovirus) (Panleukopenia, Feline Herpes and Calicivirus) rather than non-core diseases. Although we can also titer for some of these vaccines if desired.
Rabies Exception: While rabies titers can be tested, they are rarely accepted by law in lieu of required rabies vaccination. However, they can sometimes be used for boarding and grooming and daycare facilities as proof of immunity.
When to Use:
To determine if a booster is needed, often every 2-3 years.
For pets with a history of severe vaccine adverse reactions.
To check if puppies/kittens responded to their initial vaccine series.
Limitations: High antibody levels do not guarantee 100% protection, just like vaccination, and conversely, low titers do not always mean a pet is susceptible, as memory cells may still provide immunity. Every pet is an individual.
Process: A veterinarian and technician draw the blood and sends it to a laboratory for analysis.
Costs: Titer tests often cost more than the vaccines themselves, but it’s hard to put a price on individualized care.
