Nothing can determine how much *immunity* an animal has, unfortunately. Titers only tell you how many disease-fighting antibodies are present in the blood. Quote from: http://www.caberfeidh.com/Titers.htm "A titer test does not and cannot measure immunity, because immunity to specific viruses is reliant not on antibodies, but on memory cells, which we have no way to measure." Lots of good info on the above page - check it out! Titers are certainly better than revaccinating, but don't necessarily tell you much. "So what does a low or zero titer tell you? Nothing much. A high titer is strongly correlated with either recent infection or good immunity, but the opposite isn't true."
