| Additional information | Tularemia antibody titers ≥ 1:20 are of diagnostic significance. However, titers in this range may also indicate previous infection. Antibody begins to appear 2-3 weeks post-onset and generally peaks at approximately 5 weeks into the disease. Based on the antibody production pattern, a second specimen will usually demonstrate a diagnostic four fold rise for patients with active disease. |
