Comments: Tularemia AB titers >= 1:20 are of diagnostic significance. However, titers in this range may also indicate previous infection. Antibody begins to appear 2-3 weeks into the disease. Based on this antibody production pattern, a second specimen will usually demonstrate a diagnostic four-fold rise in titer for patients with active disease.
