Titre testing can be used to determine whether or not your pet is in need of a vaccine, by testing the presence of immunity for specific diseases. This is done by taking a blood sample, from which the presence of antibodies is tested. This then shows whether your pet has a natural immunity, meaning a vaccine is not required for them to be safe from contracting an illness. Titre testing can be especially useful on animals with an unknown vaccination history, to avoid unnecessary shots.
Many experts believe that titre testing can be more effective and reliable for ensuring immunity than vaccination, as it shows the actual immune response, rather than the attempt to cause an immune response which isn’t always guaranteed.
