Enzyme-Linked Immunosorbent Assay (ELISA)
Aiding in the diagnosis of tularemia.
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 this antibody production pattern, a second specimen will usually demonstrate a diagnostic four fold rise in titer for patients with active disease.
