Titer: a measurement of the amount or concentration of a substance in a solution. It usually refers to the amount of antibodies found in a patient’s blood.
A titer test can help indicate whether your pet is still protected by past vaccinations, giving you valuable information to help you decide about future vaccinations.
If titer tests on any pet, no matter the age, indicate vaccine levels are low, we recommend a booster for only the specific virus or viruses that titered low, and only for those to which the animal has a real risk of exposure.
Over-vaccination may be the cause of chronic health problems in some dogs, and titer testing can help us determine if there is a need for booster vaccinations.
