Antibody titer testing explained
A blood test checking whether vaccine antibodies still protect — used to decide if adult pets need boosters and to avoid over-vaccination. Core vaccine titers (distemper/parvo, panleukopenia) correlate strongly with protection.
🧾 Before the test
- ✓No fasting
- ✓Wait at least 2-4 weeks after the last vaccine
- ✓Rabies titers need specific labs
📊 Reading the key values
| Search | High | Low |
|---|---|---|
| Core antibodies (distemper/parvo, panleukopenia) | Protected — no booster needed | Insufficient — vaccinate |
| Rabies antibody | Protected (local law still applies) | Booster per regulation |
💡 How to read it WSAVA supports titer-guided vaccination: booster 1 year after the juvenile series, then every 2-3 years or by titer. Titers are more scientific — and usually cheaper — than automatic annual shots.

FAQ
What titer counts as protected?
Standards vary by lab; the report gives reference ranges — above the protective threshold means no booster needed.
Are titers expensive?
A few hundred per panel; every 2-3 years it's usually cheaper than annual shots and avoids over-vaccination.
